linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities

It was discovered that the framebuffer driver on the Linux kernel did not
verify size limits when changing font or screen size, leading to an out-of-
bounds write. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2021-33655)

It was discovered that the virtual terminal driver in the Linux kernel did
not properly handle VGA console font changes, leading to an out-of-bounds
write. A local attacker could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2021-33656)

Christian Brauner discovered that the XFS file system implementation in the
Linux kernel did not properly handle setgid file creation. A local attacker
could use this to gain elevated privileges. (CVE-2021-4037)

It was discovered that the ext4 file system implementation in the Linux
kernel did not properly initialize memory in some situations. A privileged
local attacker could use this to expose sensitive information (kernel
memory). (CVE-2022-0850)

Duoming Zhou discovered that the AX.25 amateur radio protocol
implementation in the Linux kernel did not handle detach events properly in
some situations. A local attacker could possibly use this to cause a denial
of service (system crash) or execute arbitrary code. (CVE-2022-1199)

Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol
implementation in the Linux kernel during device detach operations. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2022-1204)

Norbert Slusarek discovered that a race condition existed in the perf
subsystem in the Linux kernel, resulting in a use-after-free vulnerability.
A privileged local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-1729)

It was discovered that the Packet network protocol implementation in the
Linux kernel contained an out-of-bounds access. A remote attacker could use
this to expose sensitive information (kernel memory). (CVE-2022-20368)

It was discovered that the Open vSwitch implementation in the Linux kernel
contained an out of bounds write vulnerability in certain situations. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2022-2639)

Jann Horn discovered that the ASIX AX88179/178A USB Ethernet driver in the
Linux kernel contained multiple out-of-bounds vulnerabilities. A local
attacker with physical access could plug in a specially crafted USB device
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-2964)

Hao Sun and Jiacheng Xu discovered that the NILFS file system
implementation in the Linux kernel contained a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-2978)

Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in
the Linux kernel. A local attacker could use this to cause a denial of
service (system crash) or possibly expose sensitive information (kernel
memory). (CVE-2022-3028)

It was discovered that the Journaled File System (JFS) in the Linux kernel
contained a null pointer dereference in some situations. A local attacker
could use this to cause a denial of service (system crash). (CVE-2022-3202)

Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter
subsystem in the Linux kernel did not properly handle rules that truncated
packets below the packet header size. When such rules are in place, a
remote attacker could possibly use this to cause a denial of service
(system crash). (CVE-2022-36946)
