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 Android kernel in     F2FS driver there is a possible out of bounds read due     to a missing bounds check. This could lead to local     information disclosure with system execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2019-9445)In calc_vm_may_flags of     ashmem.c, there is a possible arbitrary write to shared     memory due to a permissions bypass. This could lead to     local escalation of privilege by corrupting memory     shared between processes, with no additional execution     privileges needed. User interaction is not needed for     exploitation. Product: Android Versions: Android kernel     Android ID: A-142938932(CVE-2020-0009)A new domain     bypass transient execution attack known as Special     Register Buffer Data Sampling (SRBDS) has been found.
    This flaw allows data values from special internal     registers to be leaked by an attacker able to execute     code on any core of the CPU. An unprivileged, local     attacker can use this flaw to infer values returned by     affected instructions known to be commonly used during     cryptographic operations that rely on uniqueness,     secrecy, or both.(CVE-2020-0543)A flaw was found in the     Linux kernel's implementation of the BTRFS file system.
    A local attacker, with the ability to mount a file     system, can create a use-after-free memory fault after     the file system has been unmounted. This may lead to     memory corruption or privilege     escalation.(CVE-2019-19377)A NULL pointer dereference     flaw may occur in the Linux kernel's relay_open in     kernel/relay.c. if the alloc_percpu() function is not     validated in time of failure and used as a valid     address for access. An attacker could use this flaw to     cause a denial of service.(CVE-2019-19462)A NULL     pointer dereference flaw was found in     tw5864_handle_frame function in     drivers/media/pci/tw5864/tw5864-video.c in the TW5864     Series Video media driver. The pointer 'vb' is     assigned, but not validated before its use, and can     lead to a denial of service. This flaw allows a local     attacker with special user or root privileges to crash     the system or leak internal kernel     information.(CVE-2019-20806)go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)An issue was     discovered in the Linux kernel before 5.0.6. In     rx_queue_add_kobject() and netdev_queue_add_kobject()     in net/coreet-sysfs.c, a reference count is mishandled,     aka CID-a3e23f719f5c.(CVE-2019-20811)A flaw was found     in the way the af_packet functionality in the Linux     kernel handled the retirement timer setting for     TPACKET_v3 when getting settings from the underlying     network device errors out. This flaw allows a local     user who can open the af_packet domain socket and who     can hit the error path, to use this vulnerability to     starve the system.(CVE-2019-20812)A NULL pointer     dereference flaw was found in the Linux kernel's     SELinux subsystem. 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)A flaw was found in the Linux     kernel's SELinux LSM hook implementation, where it     anticipated the skb would only contain a single Netlink     message. The hook incorrectly validated the first     Netlink message in the skb only, to allow or deny the     rest of the messages within the skb with the granted     permissions and without further processing. At this     time, there is no known ability for an attacker to     abuse this flaw.(CVE-2020-10751)A flaw was found in the     Linux Kernel in versions after 4.5-rc1 in the way     mremap handled DAX Huge Pages. This flaw allows a local     attacker with access to a DAX enabled storage to     escalate their privileges on the     system.(CVE-2020-10757)A logic bug flaw was found in     the Linux kernel's implementation of SSBD. A bug in the     logic handling allows an attacker with a local account     to disable SSBD protection during a context switch when     additional speculative execution mitigations are in     place. This issue was introduced when the per     task/process conditional STIPB switching was added on     top of the existing SSBD switching. The highest threat     from this vulnerability is to     confidentiality.(CVE-2020-10766)A flaw was found in the     Linux kernel's implementation of the Enhanced IBPB     (Indirect Branch Prediction Barrier). The IBPB     mitigation will be disabled when STIBP is not available     or when the Enhanced Indirect Branch Restricted     Speculation (IBRS) is available. This flaw allows a     local attacker to perform a Spectre V2 style attack     when this configuration is active. The highest threat     from this vulnerability is to     confidentiality.(CVE-2020-10767)A flaw was found in the     prctl() function, where it can be used to enable     indirect branch speculation after it has been disabled.
    This call incorrectly reports it as being 'force     disabled' when it is not and opens the system to     Spectre v2 attacks. The highest threat from this     vulnerability is to confidentiality.(CVE-2020-10768)A     flaw was found in the ZRAM kernel module, where a user     with a local account and the ability to read the     /sys/class/zram-control/hot_add file can create ZRAM     device nodes in the /dev/ directory. This read     allocates kernel memory and is not accounted for a user     that triggers the creation of that ZRAM device. With     this vulnerability, continually reading the device may     consume a large amount of system memory and cause the     Out-of-Memory (OOM) killer to activate and terminate     random userspace processes, possibly making the system     inoperable.(CVE-2020-10781)A stack buffer overflow     issue was found in the get_raw_socket() routine of the     Host kernel accelerator for virtio net (vhost-net)     driver. It could occur while doing an     ictol(VHOST_NET_SET_BACKEND) call, and retrieving     socket name in a kernel stack variable via     get_raw_socket(). A user able to perform ioctl(2) calls     on the '/dev/vhost-net' device may use this flaw to     crash the kernel resulting in DoS     issue.(CVE-2020-10942)A flaw was found in the Linux     kernel's implementation of the pivot_root syscall. This     flaw allows a local privileged user (root outside or     root inside a privileged container) to exploit a race     condition to manipulate the reference count of the root     filesystem. To be able to abuse this flaw, the process     or user calling pivot_root must have advanced     permissions. The highest threat from this vulnerability     is to system availability.(CVE-2020-12114)A     use-after-free flaw was found in usb_sg_cancel in     drivers/usb/core/message.c in the USB core subsystem.
    This flaw allows a local attacker with a special user     or root privileges to crash the system due to a race     problem in the scatter-gather cancellation and transfer     completion in usb_sg_wait. This vulnerability can also     lead to a leak of internal kernel     information.(CVE-2020-12464)A memory overflow and data     corruption flaw were found in the Mediatek MT76 driver     module for WiFi in mt76_add_fragment in     driverset/wireless/mediatek/mt76/dma.c. An oversized     packet with too many rx fragments causes an overflow     and corruption in memory of adjacent pages. A local     attacker with a special user or root privileges can     cause a denial of service or a leak of internal kernel     information.(CVE-2020-12465)A vulnerability was found     in __mptctl_ioctl in drivers/message/fusion/mptctl.c in     Fusion MPT base driver 'mptctl' in the SCSI device     module, where an incorrect lock leads to a race     problem. This flaw allows an attacker with local access     and special user (or root) privileges to cause a denial     of service.(CVE-2020-12652)A flaw was found in the way     the mwifiex_cmd_append_vsie_tlv() in Linux kernel's     Marvell WiFi-Ex driver handled vendor specific     information elements. A local user could use this flaw     to escalate their privileges on the     system.(CVE-2020-12653)A flaw was found in the Linux     kernel. The Marvell mwifiex driver allows a remote WiFi     access point to trigger a heap-based memory buffer     overflow due to an incorrect memcpy operation. The     highest threat from this vulnerability is to data     integrity and system availability.(CVE-2020-12654)A     flaw was discovered in the XFS source in the Linux     kernel. This flaw allows an attacker with the ability     to mount an XFS filesystem, to trigger a denial of     service while attempting to sync a file located on an     XFS v5 image with crafted metadata.(CVE-2020-12655)An     out-of-bounds (OOB) memory access flaw was found in the     Network XDP (the eXpress Data Path) module in the Linux     kernel's xdp_umem_reg function in net/xdp/xdp_umem.c.
    When a user with special user privilege of     CAP_NET_ADMIN (or root) calls setsockopt to register     umem ring on XDP socket, passing the headroom value     larger than the available space in the chunk, it leads     to an out-of-bounds write, causing panic or possible     memory corruption. This flaw may lead to privilege     escalation if a local end-user is granted permission to     influence the execution of code in this     manner.(CVE-2020-12659)A vulnerability was found in     sg_write in drivers/scsi/sg.c in the SCSI generic (sg)     driver subsystem. This flaw allows an attacker with     local access and special user or root privileges to     cause a denial of service if the allocated list is not     cleaned with an invalid (Sg_fd * sfp) pointer at the     time of failure, also possibly causing a kernel     internal information leak problem.(CVE-2020-12770)An     issue was discovered in the Linux kernel through     5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c     has a deadlock if a coalescing operation     fails.(CVE-2020-12771)A flaw was found in the Linux     kernel loose validation of child/parent process     identification handling while filtering signal     handlers. A local attacker is able to abuse this flaw     to bypass checks to send any signal to a privileged     process.(CVE-2020-12826)A flaw was found in the Linux     kernel, where it allows userspace processes, for     example, a guest VM, to directly access h/w devices via     its VFIO driver modules. The VFIO modules allow users     to enable or disable access to the devices' MMIO memory     address spaces. If a user attempts to access the     read/write devices' MMIO address space when it is     disabled, some h/w devices issue an interrupt to the     CPU to indicate a fatal error condition, crashing the     system. This flaw allows a guest user or process to     crash the host system resulting in a denial of     service.(CVE-2020-12888)gadget_dev_desc_UDC_store in     drivers/usb/gadget/configfs.c in the Linux kernel     through 5.6.13 relies on kstrdup without considering     the possibility of an internal '\0' value, which allows     attackers to trigger an out-of-bounds read, aka     CID-15753588bcd4.(CVE-2020-13143)** DISPUTED ** An     issue was discovered in the Linux kernel through 5.7.1.
    drivers/tty/vt/keyboard.c has an integer overflow if     k_ascii is called several times in a row, aka     CID-b86dab054059. NOTE: Members in the community argue     that the integer overflow does not lead to a security     issue in this case.(CVE-2020-13974)A use-after-free     flaw was found in slcan_write_wakeup in     driverset/can/slcan.c in the serial CAN module slcan. A     race condition occurs when communicating with can using     slcan between the write (scheduling the transmit) and     closing (flushing out any pending queues) the SLCAN     channel. This flaw allows a local attacker with special     user or root privileges to cause a denial of service or     a kernel information leak. The highest threat from this     vulnerability is to system     availability.(CVE-2020-14416)In the Linux kernel     through 5.7.6, usbtest_disconnect in     drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)The Linux kernel     through 5.7.11 allows remote attackers to make     observations that help to obtain sensitive information     about the internal state of the network RNG, aka     CID-f227e3ec3b5c. This is related to     drivers/char/random.c and     kernel/time/timer.c.(CVE-2020-16166)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 null pointer     dereference in the Linux kernel cgroupv2 subsystem in     versions before 5.7.10 was found in the way when reboot     the system. A local user could use this flaw to crash     the system or escalate their privileges on the     system.(CVE-2020-14356)The Linux kernel 4.9.x before     4.9.233, 4.14.x before 4.14.194, and 4.19.x before     4.19.140 has a use-after-free because skcd->no_refcnt     was not considered during a backport of a     CVE-2020-14356 patch. This is related to the cgroups     feature.(CVE-2020-25220)get_gate_page in mm/gup.c in     the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows     privilege escalation because of incorrect reference     counting (caused by gate page mishandling) of the     struct page that backs the vsyscall page. The result is     a refcount underflow. This can be triggered by any     64-bit process that can use ptrace() or     process_vm_readv(), aka     CID-9fa2dd946743.(CVE-2020-25221)In the Linux kernel     through 5.8.7, local attackers able to inject conntrack     netlink configuration could overflow a local buffer,     causing crashes or triggering use of incorrect protocol     numbers in ctnetlink_parse_tuple_filter in     net/netfilter/nf_conntrack_netlink.c, aka     CID-1cc5ef91d2ff.(CVE-2020-25211)A buffer over-read     flaw was found in RH kernel versions before 5.0 in     crypto_authenc_extractkeys in crypto/authenc.c in the     IPsec Cryptographic algorithm's module, authenc. When a     payload longer than 4 bytes, and is not following     4-byte alignment boundary guidelines, it causes a     buffer over-read threat, leading to a system crash.
    This flaw allows a local attacker with user privileges     to cause a denial of service.(CVE-2020-10769)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)In cdev_get of char_dev.c,     there is a possible use-after-free due to a race     condition. This could lead to local escalation of     privilege with System execution privileges needed. User     interaction is not needed for exploitation.Product:

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

  - The Linux kernel through 5.7.11 allows remote attackers     to make observations that help to obtain sensitive     information about the internal state of the network     RNG, aka CID-f227e3ec3b5c. This is related to     drivers/char/random.c and     kernel/time/timer.c.(CVE-2020-16166)

  - 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)

  - A buffer over-read flaw was found in RH kernel versions     before 5.0 in crypto_authenc_extractkeys in     crypto/authenc.c in the IPsec Cryptographic algorithm's     module, authenc. When a payload longer than 4 bytes,     and is not following 4-byte alignment boundary     guidelines, it causes a buffer over-read threat,     leading to a system crash. This flaw allows a local     attacker with user privileges to cause a denial of     service.(CVE-2020-10769)

  - An issue was discovered in the Linux kernel through     5.7.1. drivers/tty/vt/keyboard.c has an integer     overflow if k_ascii is called several times in a row,     aka CID-b86dab054059. NOTE: Members in the community     argue that the integer overflow does not lead to a     security issue in this case.(CVE-2020-13974)

  - In the Linux kernel through 5.7.6, usbtest_disconnect     in drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)

  - The VFIO PCI driver in the Linux kernel through 5.6.13     mishandles attempts to access disabled memory     space.(CVE-2020-12888)

  - go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)

  - An issue was discovered in the Linux kernel before     5.0.6. In rx_queue_add_kobject() and     netdev_queue_add_kobject() in net/core/net-sysfs.c, a     reference count is mishandled, aka     CID-a3e23f719f5c.(CVE-2019-20811)

  - An issue was discovered in the Linux kernel before     5.4.7. The prb_calc_retire_blk_tmo() function in     net/packet/af_packet.c can result in a denial of     service (CPU consumption and soft lockup) in a certain     failure case involving TPACKET_V3, aka     CID-b43d1f9f7067.(CVE-2019-20812)

  - 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 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)

  - gadget_dev_desc_UDC_store in     drivers/usb/gadget/configfs.c in the Linux kernel     through 5.6.13 relies on kstrdup without considering     the possibility of an internal '\0' value, which allows     attackers to trigger an out-of-bounds read, aka     CID-15753588bcd4.(CVE-2020-13143)

  - 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)

  - The __mptctl_ioctl function in     drivers/message/fusion/mptctl.c in the Linux kernel     before 5.4.14 allows local users to hold an incorrect     lock during the ioctl operation and trigger a race     condition, i.e., a 'double fetch' vulnerability, aka     CID-28d76df18f0a. NOTE: the vendor states 'The security     impact of this bug is not as bad as it could have been     because these operations are all privileged and root     already has enormous destructive     power.'(CVE-2020-12652)

  - An issue was found in Linux kernel before 5.5.4. The     mwifiex_cmd_append_vsie_tlv() function in     drivers/net/wireless/marvell/mwifiex/scan.c allows     local users to gain privileges or cause a denial of     service because of an incorrect memcpy and buffer     overflow, aka CID-b70261a288ea.(CVE-2020-12653)

  - An issue was found in Linux kernel before 5.5.4.
    mwifiex_ret_wmm_get_status() in     drivers/net/wireless/marvell/mwifiex/wmm.c allows a     remote AP to trigger a heap-based buffer overflow     because of an incorrect memcpy, aka     CID-3a9b153c5591.(CVE-2020-12654)

  - An issue was discovered in xfs_agf_verify in     fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through     5.6.10. Attackers may trigger a sync of excessive     duration via an XFS v5 image with crafted metadata, aka     CID-d0c7feaf8767.(CVE-2020-12655)

  - A flaw was found in the Linux kernel's implementation     of GRO in versions before 5.2. This flaw allows an     attacker with local access to crash the     system.(CVE-2020-10720)

  - 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)

  - 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)

  - 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)

  - In the netlink driver, there is a possible out of     bounds write due to a race condition. This could lead     to local escalation of privilege with System execution     privileges needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-65025077(CVE-2020-0066)

  - 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 slc_bump in     drivers/net/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. 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 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)

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

According to the versions of the kernel packages installed, the EulerOS 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):An information leak flaw     was found in the way the Linux kernel's Bluetooth stack     implementation handled initialization of stack memory     when handling certain AMP packets. A remote attacker in     adjacent range could use this flaw to leak small     portions of stack memory on the system by sending a     specially crafted AMP packets. The highest threat from     this vulnerability is to data     confidentiality.(CVE-2020-12352)A flaw was found in the     way the Linux kernel Bluetooth implementation handled     L2CAP packets with A2MP CID. A remote attacker in     adjacent range could use this flaw to crash the system     causing denial of service or potentially execute     arbitrary code on the system by sending a specially     crafted L2CAP packet. The highest threat from this     vulnerability is to data confidentiality and integrity     as well as system availability.(CVE-2020-12351)A heap     buffer overflow flaw was found in the way the Linux     kernel's Bluetooth implementation processed extended     advertising report events. This flaw allows a remote     attacker in an adjacent range to crash the system,     causing a denial of service or to potentially execute     arbitrary code on the system by sending a specially     crafted Bluetooth packet. The highest threat from this     vulnerability is to confidentiality, integrity, as well     as system availability.(CVE-2020-24490)A flaw was found     in the Linux kernel in versions before 5.9-rc7. Traffic     between two Geneve endpoints may be unencrypted when     IPsec is configured to encrypt traffic for the specific     UDP port used by the GENEVE tunnel allowing anyone     between the two endpoints to read the traffic     unencrypted. The main threat from this vulnerability is     to data confidentiality.(CVE-2020-25645)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)A missing CAP_NET_RAW     check in NFC socket creation in netfc/rawsock.c in the     Linux kernel before 5.8.2 could be used by local     attackers to create raw sockets, bypassing security     mechanisms, aka CID-26896f01467a.(CVE-2020-26088)perf:
    Fix race in perf_mmap_close function(CVE-2020-14351)A     flaw was found in the Linux kernel before 5.9-rc4.
    Memory corruption can be exploited to gain root     privileges from unprivileged processes. The highest     threat from this vulnerability is to data     confidentiality and integrity.(CVE-2020-14386)A flaw     was found in the HDLC_PPP module of the Linux kernel in     versions before 5.9-rc7. Memory corruption and a read     overflow is caused by improper input validation in the     ppp_cp_parse_cr function which can cause the system to     crash or cause a denial of service. The highest threat     from this vulnerability is to data confidentiality and     integrity as well as system     availability.(CVE-2020-25643)The Linux kernel, as used     in Red Hat Enterprise Linux 7, kernel-rt, and     Enterprise MRG 2 and when booted with UEFI Secure Boot     enabled, allows local users to bypass intended     securelevel/secureboot restrictions by leveraging     improper handling of secure_boot flag across kexec     reboot.(CVE-2015-7837)A flaw was found in the Linux     kernel's implementation of biovecs in versions before     5.9-rc7. A zero-length biovec request issued by the     block subsystem could cause the kernel to enter an     infinite loop, causing a denial of service. This flaw     allows a local attacker with basic privileges to issue     requests to a block device, resulting in a denial of     service. The highest threat from this vulnerability is     to system availability.(CVE-2020-25641)A memory     out-of-bounds read flaw was found in the Linux kernel     before 5.9-rc2 with the ext3/ext4 file system, in the     way it accesses a directory with broken indexing. This     flaw allows a local user to crash the system if the     directory exists. The highest threat from this     vulnerability is to system     availability.(CVE-2020-14314)In skb_to_mamac of     networking.c, there is a possible out of bounds write     due to an integer overflow. This could lead to local     escalation of privilege with no additional execution     privileges needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID:
    A-143560807(CVE-2020-0432)get_gate_page in mm/gup.c in     the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows     privilege escalation because of incorrect reference     counting (caused by gate page mishandling) of the     struct page that backs the vsyscall page. The result is     a refcount underflow. This can be triggered by any     64-bit process that can use ptrace() or     process_vm_readv(), aka     CID-9fa2dd946743.(CVE-2020-25285)
