In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The timeri variable was originally intended to be for a newly created timer instance, but was used for a different purpose after refactoring.

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  - ** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c     in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by     triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of     this because it occurs on a code path where a successful allocation has already occurred. (CVE-2019-19055)

  - In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code     refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The     timeri variable was originally intended to be for a newly created timer instance, but was used for a     different purpose after refactoring. (CVE-2019-19807)

  - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new     filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the     current umask is not considered. (CVE-2020-24394)

  - An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI     subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the     pointer to an iscsi_transport struct in the kernel module's global variables. (CVE-2021-27363)

  - An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a     Netlink message. (CVE-2021-27365)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has kernel packages installed that are affected by multiple vulnerabilities:

  - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an     out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)

  - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when     hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)

  - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through     5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21. (CVE-2019-17055)

  - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel     through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.
    (CVE-2019-18808)

  - ** DISPUTED ** A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c     in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by     triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of     this because an attacker cannot realistically control this failure at probe time. (CVE-2019-19046)

  - ** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c     in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by     triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of     this because it occurs on a code path where a successful allocation has already occurred. (CVE-2019-19055)

  - An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way     the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID     features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use     this flaw to crash the system, resulting in a denial of service. (CVE-2019-19332)

  - In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79. (CVE-2019-19523)

  - In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9. (CVE-2019-19524)

  - In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB     device in the drivers/usb/class/cdc-acm.c driver, aka CID-c52873e5a1ef. (CVE-2019-19530)

  - In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device     in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29. (CVE-2019-19534)

  - In the Linux kernel before 5.2.10, there is a race condition bug that can be caused by a malicious USB     device in the USB character device driver layer, aka CID-303911cfc5b9. This affects     drivers/usb/core/file.c. (CVE-2019-19537)

  - In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code     refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The     timeri variable was originally intended to be for a newly created timer instance, but was used for a     different purpose after refactoring. (CVE-2019-19807)

  - In the Linux kernel before 5.4.12, drivers/input/input.c has out-of-bounds writes via a crafted keycode     table, as demonstrated by input_set_keycode, aka CID-cb222aed03d7. (CVE-2019-20636)

  - In the Android kernel in i2c driver there is a possible out of bounds write due to memory corruption. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9454)

  - In the Android kernel in the video driver there is a use after free due to a race condition. This could     lead to local escalation of privilege with no additional execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9458)

  - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an     attacker with a local account to crash a trivial program and exfiltrate private kernel data.
    (CVE-2020-10732)

  - A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS     client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause     a kernel panic. The highest threat from this vulnerability is to data confidentiality and system     availability. (CVE-2020-10742)

  - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it     incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly     only validate the first netlink message in the skb and allow or deny the rest of the messages within the     skb with the granted permission without further processing. (CVE-2020-10751)

  - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c     has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing,     aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability     because the issue is a bug in parsing mount options which can only be specified by a privileged user, so     triggering the bug does not grant any powers not already held.. (CVE-2020-11565)

  - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)

  - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection     tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote     user to crash the system, causing a denial of service. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-14305)

  - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers     to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c     instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)

  - The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete     permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap     rbd block devices, aka CID-f44d04e696fe. (CVE-2020-25284)

  - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest     when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into     accessing sensitive L1 resources that should be inaccessible to the L2 guest. (CVE-2020-2732)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in     drivers/tty/vt/vt.c. (CVE-2020-8647)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region     function in drivers/video/console/vgacon.c. (CVE-2020-8649)

  - An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to     a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it,     aka CID-2e90ca68b0d2. (CVE-2020-9383)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

  - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel     through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket,     aka CID-e69dbd4619e7. (CVE-2019-17053)

  - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through     5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21. (CVE-2019-17055)

  - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel     through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.
    (CVE-2019-18808)

  - A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of this because     an attacker cannot realistically control this failure at probe time (CVE-2019-19046)

  - A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     nl80211hdr_put() failures, aka CID-1399c59fa929.

  - In the Android kernel in i2c driver there is a possible out of bounds write due to memory corruption. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9454)

  - In the Android kernel in the video driver there is a use after free due to a race condition. This could     lead to local escalation of privilege with no additional execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9458)

  - There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of     ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device     file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed,     it can cause an exploitable condition as the process wakes up to terminate and clean all attached files.
    The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the     inode. (CVE-2020-10690)

  - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an     attacker with a local account to crash a trivial program and exfiltrate private kernel data.
    (CVE-2020-10732)

  - A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS     client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause     a kernel panic. The highest threat from this vulnerability is to data confidentiality and system     availability. (CVE-2020-10742)

  - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it     incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly     only validate the first netlink message in the skb and allow or deny the rest of the messages within the     skb with the granted permission without further processing. (CVE-2020-10751)

  - In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family     field, which might allow attackers to trigger kernel stack corruption via crafted system calls.
    (CVE-2020-10942)

  - An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-     based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-     aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the     issue is a bug in parsing mount options which can only be specified by a privileged user, so triggering     the bug does not grant any powers not already held. (CVE-2020-11565)

  - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)

  - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in     a different security domain. Exploitation limitations include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where signals to a parent process present a substantial     operational threat. (CVE-2020-12826)

  - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection     tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote     user to crash the system, causing a denial of service. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-14305)

  - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN     and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't     correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would     allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this     vulnerability is to data confidentiality. (CVE-2020-1749)

  - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest     when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into     accessing sensitive L1 resources that should be inaccessible to the L2 guest. (CVE-2020-2732)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in     drivers/tty/vt/vt.c. (CVE-2020-8647)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region     function in drivers/video/console/vgacon.c. (CVE-2020-8649)

  - An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to     a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it,     aka CID-2e90ca68b0d2. (CVE-2020-9383)

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc. Security Fix(es):In the Linux kernel     before 5.2.9, there is an info-leak bug that can be     caused by a malicious USB device in the     driverset/can/usb/peak_usb/pcan_usb_pro.c driver, aka     CID-ead16e53c2f0.(CVE-2019-19536)In the Linux kernel     before 5.2.9, there is an info-leak bug that can be     caused by a malicious USB device in the     driverset/can/usb/peak_usb/pcan_usb_fd.c driver, aka     CID-30a8beeb3042.(CVE-2019-19535)vcs_write in     drivers/tty/vt/vc_screen.c in the Linux kernel through     5.3.13 does not prevent write access to vcsu devices,     aka CID-0c9acb1af77a.(CVE-2019-19252)In the AppleTalk     subsystem in the Linux kernel before 5.1, there is a     potential NULL pointer dereference because     register_snap_client may return NULL. This will lead to     denial of service in net/appletalk/aarp.c and     net/appletalk/ddp.c, as demonstrated by     unregister_snap_client, aka     CID-9804501fa122.(CVE-2019-19227)A memory leak in the     adis_update_scan_mode() function in     drivers/iio/imu/adis_buffer.c in the Linux kernel     before 5.3.9 allows attackers to cause a denial of     service (memory consumption), aka     CID-ab612b1daf41.(CVE-2019-19060)In the Linux kernel     before 5.3.11, there is an info-leak bug that can be     caused by a malicious USB device in the     driverset/can/usb/peak_usb/pcan_usb_core.c driver, aka     CID-f7a1337f0d29.(CVE-2019-19534)In the Linux kernel     before 5.3.11, there is a use-after-free bug that can     be caused by a malicious USB device in the     driverset/can/usb/mcba_usb.c driver, aka     CID-4d6636498c41.(CVE-2019-19529)In the Linux kernel     before 5.3.9, there is a use-after-free bug that can be     caused by a malicious USB device in the     driversfc/pn533/usb.c driver, aka     CID-6af3aa57a098.(CVE-2019-19526)In the Linux kernel     before 5.3.6, there is a use-after-free bug that can be     caused by a malicious USB device in the     driverset/ieee802154/atusb.c driver, aka     CID-7fd25e6fc035.(CVE-2019-19525)In the Linux kernel     before 5.3.9, there are multiple out-of-bounds write     bugs that can be caused by a malicious USB device in     the Linux kernel HID drivers, aka CID-d9d4b1e46d95.
    This affects drivers/hid/hid-axff.c,     drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c,     drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c,     drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c,     drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c,     drivers/hid/hid-tmff.c, and     drivers/hid/hid-zpff.c.(CVE-2019-19532)In the Linux     kernel before 5.2.10, there is a use-after-free bug     that can be caused by a malicious USB device in the     drivers/hid/usbhid/hiddev.c driver, aka     CID-9c09b214f30e.(CVE-2019-19527)** DISPUTED ** The     Linux kernel through 5.0.7, when CONFIG_IA32_AOUT is     enabled and ia32_aout is loaded, allows local users to     bypass ASLR on setuid a.out programs (if any exist)     because install_exec_creds() is called too late in     load_aout_binary() in fs/binfmt_aout.c, and thus the     ptrace_may_access() check has a race condition when     reading /proc/pid/stat. NOTE: the software maintainer     disputes that this is a vulnerability because ASLR for     a.out format executables has never been     supported.(CVE-2019-11191)In the Linux kernel before     5.3.12, there is a use-after-free bug that can be     caused by a malicious USB device in the     drivers/input/ff-memless.c driver, aka     CID-fa3a5a1880c9.(CVE-2019-19524)driverset/wireless/mar     vell/libertas/if_sdio.c in the Linux kernel 5.2.14 does     not check the alloc_workqueue return value, leading to     a NULL pointer     dereference.(CVE-2019-16232)driverset/fjes/fjes_main.c     in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer     dereference.(CVE-2019-16231)** DISPUTED **     drivers/gpu/drm/amd/amdkfd/kfd_interrupt.c in the Linux     kernel 5.2.14 does not check the alloc_workqueue return     value, leading to a NULL pointer dereference. NOTE: The     security community disputes this issues as not being     serious enough to be deserving a CVE     id.(CVE-2019-16229)Linux kernel CIFS implementation,     version 4.9.0 is vulnerable to a relative paths     injection in directory entry lists.(CVE-2019-10220)A     heap overflow flaw was found in the Linux kernel, all     versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi     chip driver. The vulnerability allows a remote attacker     to cause a system crash, resulting in a denial of     service, or execute arbitrary code. The highest threat     with this vulnerability is with the availability of the     system. If code execution occurs, the code will run     with the permissions of root. This will affect both     confidentiality and integrity of files on the     system.(CVE-2019-14901)The Linux kernel before 5.4.2     mishandles ext4_expand_extra_isize, as demonstrated by     use-after-free errors in __ext4_expand_extra_isize and     ext4_xattr_set_entry, related to fs/ext4/inode.c and     fs/ext4/super.c, aka CID-4ea99936a163.(CVE-2019-19767)A     heap-based buffer overflow was discovered in the Linux     kernel, all versions 3.x.x and 4.x.x before 4.18.0, in     Marvell WiFi chip driver. The flaw could occur when the     station attempts a connection negotiation during the     handling of the remote devices country settings. This     could allow the remote device to cause a denial of     service (system crash) or possibly execute arbitrary     code.(CVE-2019-14895)Linux Kernel could allow a local     authenticated attacker to obtain sensitive information,     caused by a Transaction Asynchronous Abort (TAA) h/w     issue in KVM. By sending a specially-crafted request,     an attacker could exploit this vulnerability to obtain     sensitive information, and use this information to     launch further attacks against the affected     system.(CVE-2019-19338)TSX Asynchronous Abort condition     on some CPUs utilizing speculative execution may allow     an authenticated user to potentially enable information     disclosure via a side channel with local     access.(CVE-2019-11135)An out-of-bounds memory write     issue was found in the Linux Kernel, version 3.13     through 5.4, in the way the Linux kernel's KVM     hypervisor handled the 'KVM_GET_EMULATED_CPUID'     ioctl(2) request to get CPUID features emulated by the     KVM hypervisor. A user or process able to access the     '/dev/kvm' device could use this flaw to crash the     system, resulting in a denial of     service.(CVE-2019-19332)kernel/sched/fair.c in the     Linux kernel before 5.3.9, when cpu.cfs_quota_us is     used (e.g., with Kubernetes), allows attackers to cause     a denial of service against non-cpu-bound applications     by generating a workload that triggers unwanted slice     expiration, aka CID-de53fd7aedb1. (In other words,     although this slice expiration would typically be seen     with benign workloads, it is possible that an attacker     could calculate how many stray requests are required to     force an entire Kubernetes cluster into a     low-performance state caused by slice expiration, and     ensure that a DDoS attack sent that number of stray     requests. An attack does not affect the stability of     the kernel it only causes mismanagement of application     execution.)(CVE-2019-19922)A stack-based buffer     overflow was found in the Linux kernel, version     kernel-2.6.32, in Marvell WiFi chip driver. An attacker     is able to cause a denial of service (system crash) or,     possibly execute arbitrary code, when a STA works in     IBSS mode (allows connecting stations together without     the use of an AP) and connects to another     STA.(CVE-2019-14897)A heap-based buffer overflow     vulnerability was found in the Linux kernel, version     kernel-2.6.32, in Marvell WiFi chip driver. A remote     attacker could cause a denial of service (system crash)     or, possibly execute arbitrary code, when the     lbs_ibss_join_existing function is called after a STA     connects to an AP.(CVE-2019-14896)In the Linux kernel     through 5.4.6, there are information leaks of     uninitialized memory to a USB device in the     driverset/can/usb/kvaser_usb/kvaser_usb_leaf.c driver,     aka CID-da2311a6385c.(CVE-2019-19947)In the Linux     kernel before 5.1, there is a memory leak in
    __feat_register_sp() in net/dccp/feat.c, which may     cause denial of service, aka     CID-1d3ff0950e2b.(CVE-2019-20096)mwifiex_tm_cmd in     driverset/wireless/marvell/mwifiex/cfg80211.c in the     Linux kernel before 5.1.6 has some error-handling cases     that did not free allocated hostcmd memory, aka     CID-003b686ace82. This will cause a memory leak and     denial of service.(CVE-2019-20095)An exploitable     denial-of-service vulnerability exists in the Linux     kernel prior to mainline 5.3. An attacker could exploit     this vulnerability by triggering AP to send IAPP     location updates for stations before the required     authentication process has completed. This could lead     to different denial-of-service scenarios, either by     causing CAM table attacks, or by leading to traffic     flapping if faking already existing clients in other     nearby APs of the same wireless infrastructure. An     attacker can forge Authentication and Association     Request packets to trigger this     vulnerability.(CVE-2019-5108)In a Linux KVM guest that     has PV TLB enabled, a process in the guest kernel may     be able to read memory locations from another process     in the same guest. This problem is limit to the host     running linux kernel 4.10 with a guest running linux     kernel 4.16 or later. The problem mainly affects AMD     processors but Intel CPUs cannot be ruled     out.(CVE-2019-3016)fsamei.c in the Linux kernel before     5.5 has a may_create_in_sticky use-after-free, which     allows local users to cause a denial of service (OOPS)     or possibly obtain sensitive information from kernel     memory, aka CID-d0cb50185ae9. One attack vector may be     an open system call for a UNIX domain socket, if the     socket is being moved to a new parent directory and its     old parent directory is being     removed.(CVE-2020-8428)There is a use-after-free     vulnerability in the Linux kernel through 5.5.2 in the     n_tty_receive_buf_common function in     drivers/tty_tty.c.(CVE-2020-8648)An issue was     discovered in the Linux kernel through 5.5.6. set_fdc     in drivers/block/floppy.c leads to a wait_til_ready     out-of-bounds read because the FDC index is not checked     for errors before assigning it, aka     CID-2e90ca68b0d2.(CVE-2020-9383)There is a     use-after-free vulnerability in the Linux kernel     through 5.5.2 in the vgacon_invert_region function in     drivers/video/console/vgacon.c.(CVE-2020-8649)There is     a use-after-free vulnerability in the Linux kernel     through 5.5.2 in the vc_do_resize function in     drivers/tty/vt/vt.c.(CVE-2020-8647)In the Linux kernel     5.0.21, mounting a crafted ext4 filesystem image,     performing some operations, and unmounting can lead to     a use-after-free in ext4_put_super in fs/ext4/super.c,     related to dump_orphan_list in     fs/ext4/super.c.(CVE-2019-19447)A flaw was discovered     in the way that the KVM hypervisor handled instruction     emulation for an L2 guest when nested virtualisation is     enabled. Under some circumstances, an L2 guest may     trick the L0 guest into accessing sensitive L1     resources that should be inaccessible to the L2     guest.(CVE-2020-2732)In the Linux kernel before 5.3.11,     sound/core/timer.c has a use-after-free caused by     erroneous code refactoring, aka CID-e7af6307a8a5. This     is related to snd_timer_open and     snd_timer_close_locked. The timeri variable was     originally intended to be for a newly created timer     instance, but was used for a different purpose after     refactoring.(CVE-2019-19807)In the Linux kernel     5.4.0-rc2, there is a use-after-free (read) in the
    __blk_add_trace function in kernel/trace/blktrace.c     (which is used to fill out a blk_io_trace structure and     place it in a per-cpu sub-buffer).(CVE-2019-19768)In     the Linux kernel 5.0.21, mounting a crafted f2fs     filesystem image can cause a NULL pointer dereference     in f2fs_recover_fsync_data in fs/f2fs/recovery.c. This     is related to F2FS_P_SB in     fs/f2fs/f2fs.h.(CVE-2019-19815)** DISPUTED **
    __btrfs_free_extent in fs/btrfs/extent-tree.c in the     Linux kernel through 5.3.12 calls btrfs_print_leaf in a     certain ENOENT case, which allows local users to obtain     potentially sensitive information about register values     via the dmesg program. NOTE: The BTRFS development team     disputes this issues as not being a vulnerability     because '1) The kernel provide facilities to restrict     access to dmesg - dmesg_restrict=1 sysctl option. So     it's really up to the system administrator to judge     whether dmesg access shall be disallowed or not. 2)     WARN/WARN_ON are widely used macros in the linux     kernel. If this CVE is considered valid this would mean     there are literally thousands CVE lurking in the kernel
    - something which clearly is not the     case.'(CVE-2019-19039)ext4_empty_dir in fs/ext4amei.c     in the Linux kernel through 5.3.12 allows a NULL     pointer dereference because     ext4_read_dirblock(inode,0,DIRENT_HTREE) can be     zero.(CVE-2019-19037)btrfs_root_node in     fs/btrfs/ctree.c in the Linux kernel through 5.3.12     allows a NULL pointer dereference because     rcu_dereference(root->node) can be     zero.(CVE-2019-19036)In the Linux kernel 4.19.83, there     is a use-after-free (read) in the debugfs_remove     function in fs/debugfs/inode.c (which is used to remove     a file or directory in debugfs that was previously     created with a call to another debugfs function such as     debugfs_create_file).(CVE-2019-19770)An issue was     discovered in slc_bump in driverset/can/slcan.c in the     Linux kernel through 5.6.2. It allows attackers to read     uninitialized can_frame data, potentially containing     sensitive information from kernel stack memory, if the     configuration lacks CONFIG_INIT_STACK_ALL, aka     CID-b9258a2cece4.(CVE-2020-11494)An issue was     discovered in the Linux kernel through 5.6.2.
    mpol_parse_str in mm/mempolicy.c has a stack-based     out-of-bounds write because an empty nodelist is     mishandled during mount option parsing, aka     CID-aa9f7d5172fa.(CVE-2020-11565)A flaw was found in     the Linux kernel's implementation of some networking     protocols in IPsec, such as VXLAN and GENEVE tunnels     over IPv6. When an encrypted tunnel is created between     two hosts, the kernel isn't correctly routing tunneled     data over the encrypted link rather sending the data     unencrypted. This would allow anyone in between the two     endpoints to read the traffic unencrypted. The main     threat from this vulnerability is to data     confidentiality.(CVE-2020-1749)An issue was discovered     in the stv06xx subsystem in the Linux kernel before     5.6.1. drivers/media/usb/gspca/stv06xx/stv06xx.c and     drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c     mishandle invalid descriptors, as demonstrated by a     NULL pointer dereference, aka     CID-485b06aadb93.(CVE-2020-11609)An issue was     discovered in the Linux kernel before 5.6.1.
    drivers/media/usb/gspca/ov519.c allows NULL pointer     dereferences in ov511_mode_init_regs and     ov518_mode_init_regs when there are zero endpoints, aka     CID-998912346c0d.(CVE-2020-11608)In the Linux kernel     before 5.4.12, drivers/input/input.c has out-of-bounds     writes via a crafted keycode table, as demonstrated by     input_set_keycode, aka     CID-cb222aed03d7.(CVE-2019-20636)In the Linux kernel     before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c     (aka the Xirlink camera USB driver) mishandles invalid     descriptors, aka CID-a246b4d54770.(CVE-2020-11668)An     issue was discovered in the Linux kernel through 5.6.2.
    mpol_parse_str in mm/mempolicy.c has a stack-based     out-of-bounds write because an empty nodelist is     mishandled during mount option parsing, aka     CID-aa9f7d5172fa.(CVE-2020-0067)An issue was discovered     in the Linux kernel before 5.2 on the powerpc platform.
    arch/powerpc/kernel/idle_book3s.S does not have     save/restore functionality for PNV_POWERSAVE_AMR,     PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR, aka     CID-53a712bae5dd.(CVE-2020-11669)A flaw was found in     the Linux kernelaEUR?s implementation of GRO. This flaw     allows an attacker with local access to crash the     system.(CVE-2020-10720)A flaw was found in the Linux     kernel's implementation of the invert video code on VGA     consoles when a local attacker attempts to resize the     console, calling an ioctl VT_RESIZE, which causes an     out-of-bounds write to occur. This flaw allows a local     user with access to the VGA console to crash the     system, potentially escalating their privileges on the     system. The highest threat from this vulnerability is     to data confidentiality and integrity as well as system     availability.(CVE-2020-14331)An out-of-bounds (OOB)     memory access flaw was found in ttm_put_pages in     drivers/gpu/drm/ttm/ttm_page_alloc.c in the Linux     kernel's graphics module. Incrementing the page pointer     for huge pages was not in sync with the reference     counter, and this could lead to an out-of-bounds access     or a denial of service. This flaw allows a local     attacker with special user privileges (or root) to     cause memory exploitation.(CVE-2019-19927)

  - ext4_protect_reserved_inode in fs/ext4/block_validity.c     in the Linux kernel through 5.5.3 allows attackers to     cause a denial of service (soft lockup) via a crafted     journal size.(CVE-2020-8992)

  - An issue was discovered in the Linux kernel through     5.5.6. set_fdc in drivers/block/floppy.c leads to a     wait_til_ready out-of-bounds read because the FDC index     is not checked for errors before assigning it, aka     CID-2e90ca68b0d2.(CVE-2020-9383)

  - In the Linux kernel before 5.3.11, sound/core/timer.c     has a use-after-free caused by erroneous code     refactoring, aka CID-e7af6307a8a5. This is related to     snd_timer_open and snd_timer_close_locked. The timeri     variable was originally intended to be for a newly     created timer instance, but was used for a different     purpose after refactoring.(CVE-2019-19807)

  - Kernel: kvm: nVMX: L2 guest may trick the L0 hypervisor     to access sensitive L1 resources(CVE-2020-2732)

  - There is a use-after-free vulnerability in the Linux     kernel through 5.5.2 in the n_tty_receive_buf_common     function in drivers/tty/n_tty.c.(CVE-2020-8648)

  - There is a use-after-free vulnerability in the Linux     kernel through 5.5.2 in the vgacon_invert_region     function in     drivers/video/console/vgacon.c.(CVE-2020-8649)

  - There is a use-after-free vulnerability in the Linux     kernel through 5.5.2 in the vc_do_resize function in     drivers/tty/vt/vt.c.(CVE-2020-8647)

  - fs/namei.c in the Linux kernel before 5.5 has a     may_create_in_sticky use-after-free, which allows local     users to cause a denial of service (OOPS) or possibly     obtain sensitive information from kernel memory, aka     CID-d0cb50185ae9. One attack vector may be an open     system call for a UNIX domain socket, if the socket is     being moved to a new parent directory and its old     parent directory is being removed.(CVE-2020-8428)

  - In a Linux KVM guest that has PV TLB enabled, a process     in the guest kernel may be able to read memory     locations from another process in the same guest. This     problem is limit to the host running linux kernel 4.10     with a guest running linux kernel 4.16 or later. The     problem mainly affects AMD processors but Intel CPUs     cannot be ruled out.(CVE-2019-3016)
