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

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.

  - In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when     register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka     CID-07f12b26e21a. (CVE-2019-16994)

  - 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. 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)

  - A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     alloc_page() failures, aka CID-b4b814fec1a5. (CVE-2019-19058)

  - Multiple memory leaks in the iwl_pcie_ctxt_info_gen3_init() function in     drivers/net/wireless/intel/iwlwifi/pcie/ctxt-info-gen3.c in the Linux kernel through 5.3.11 allow     attackers to cause a denial of service (memory consumption) by triggering iwl_pcie_init_fw_sec() or     dma_alloc_coherent() failures, aka CID-0f4f199443fa. (CVE-2019-19059)

  - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through     5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     crypto_report_alg() failures, aka CID-ffdde5932042. (CVE-2019-19062)

  - Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the     Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka     CID-3f9361695113. (CVE-2019-19063)

  - 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 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)

  - 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 5.3.11, 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)

  - 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)

  - 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 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in     fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e. (CVE-2019-20054)

  - mwifiex_tm_cmd in drivers/net/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)

  - 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)

  - 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)

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 MAIN 6.01, has kernel packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in the Linux kernel's NFS     implementation, all versions 3.x and all versions 4.x up     to 4.20. An attacker, who is able to mount an exported     NFS filesystem, is able to trigger a null pointer     dereference by using an invalid NFS sequence. This can     panic the machine and deny access to the NFS server. Any     outstanding disk writes to the NFS server will be lost.
    (CVE-2018-16871)

  - 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)

  - The flow_dissector feature in the Linux kernel 4.3     through 5.x before 5.3.10 has a device tracking     vulnerability, aka CID-55667441c84f. This occurs because     the auto flowlabel of a UDP IPv6 packet relies on a     32-bit hashrnd value as a secret, and because jhash     (instead of siphash) is used. The hashrnd value remains     the same starting from boot time, and can be inferred by     an attacker. This affects net/core/flow_dissector.c and     related code. (CVE-2019-18282)

  - An issue was discovered in net/ipv4/sysctl_net_ipv4.c in     the Linux kernel before 5.0.11. There is a     net/ipv4/tcp_input.c signed integer overflow in     tcp_ack_update_rtt() when userspace writes a very large     integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading     to a denial of service or possibly unspecified other     impact, aka CID-19fad20d15a6. (CVE-2019-18805)

  - A memory leak in the mlx5_fpga_conn_create_cq() function     in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c     in the Linux kernel before 5.3.11 allows attackers to     cause a denial of service (memory consumption) by     triggering mlx5_vector2eqn() failures, aka     CID-c8c2a057fdc7. (CVE-2019-19045)

  - ** 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)

  - A memory leak in the bnxt_re_create_srq() function in     drivers/infiniband/hw/bnxt_re/ib_verbs.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial     of service (memory consumption) by triggering copy to     udata failures, aka CID-4a9d46a9fe14. (CVE-2019-19077)

  - 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 5.3.11, 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 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)

  - A memory leak in the kernel_read_file function in     fs/exec.c in the Linux kernel through 4.20.11 allows     attackers to cause a denial of service (memory     consumption) by triggering vfs_read failures.
    (CVE-2019-8980)

  - A NULL pointer dereference flaw was found in the Linux     kernel's SELinux subsystem in versions before 5.7. This     flaw occurs while importing the Commercial IP Security     Option (CIPSO) protocol's category bitmap into the     SELinux extensible bitmap via the'     ebitmap_netlbl_import' routine. While processing the     CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of service.
    (CVE-2020-10711)

  - In the Linux kernel through 5.6.7 on the s390 platform,     code execution may occur because of a race condition, as     demonstrated by code in enable_sacf_uaccess in     arch/s390/lib/uaccess.c that fails to protect against a     concurrent page table upgrade, aka CID-3f777e19d171. A     crash could also occur. (CVE-2020-11884)

  - An issue was discovered in the Linux kernel before     5.6.5. There is a use-after-free in block/bfq-iosched.c     related to bfq_idle_slice_timer_body. (CVE-2020-12657)

  - 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)
