  script_tag(name:"insight", value:"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. ... [Please see the references for more information on the vulnerabilities]");
