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 5.2.10, 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)

  - 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)

It is exploitable     for privilege escalation on some Linux distributions     where local users have /dev/video0 access, but only if     the driver happens to be loaded. There are multiple     race conditions during streaming stopping in this     driver (part of the V4L2 subsystem). These issues are     caused by wrong mutex locking in     vivid_stop_generating_vid_cap(),     vivid_stop_generating_vid_out(),     sdr_cap_stop_streaming(), and the corresponding     kthreads. At least one of these race conditions leads     to a use-after-free.(CVE-2019-18683)
