properly perform reference counting in some situations, leading to a use-
after-free vulnerability. A local attacker could use this to cause a denial

(CVE-2022-3910)

It was discovered that a race condition existed in the Android Binder IPC
subsystem in the Linux kernel, leading to 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-2022-20421)

David Leadbeater discovered that the netfilter IRC protocol tracking
implementation in the Linux Kernel incorrectly handled certain message
payloads in some situations. A remote attacker could possibly use this to
cause a denial of service or bypass firewall filtering. (CVE-2022-2663)

It was discovered that the sound subsystem in the Linux kernel contained a
race condition in some situations. A local attacker could use this to cause
a denial of service (system crash). (CVE-2022-3303)

It was discovered that the Sunplus Ethernet driver in the Linux kernel
contained a read-after-free vulnerability. An attacker could possibly use
this to expose sensitive information (kernel memory) (CVE-2022-3541)

It was discovered that a memory leak existed in the Unix domain socket
implementation of the Linux kernel. A local attacker could use this to
cause a denial of service (memory exhaustion). (CVE-2022-3543)

It was discovered that the NILFS2 file system implementation in the Linux
kernel did not properly deallocate memory in certain error conditions. An
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2022-3544, CVE-2022-3646)

Gwnaun Jung discovered that the SFB packet scheduling 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-2022-3586)

It was discovered that the hugetlb implementation in the Linux kernel
contained a race condition in some situations. A local attacker could use
this to cause a denial of service (system crash) or expose sensitive
information (kernel memory). (CVE-2022-3623)

Khalid Masum discovered that the NILFS2 file system implementation in the
Linux kernel did not properly handle certain error conditions, leading to a
use-after-free vulnerability. A local attacker could use this to cause a
denial of service or possibly execute arbitrary code. (CVE-2022-3649)

It was discovered that a race condition existed in the MCTP implementation
in the Linux kernel, leading to 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-2022-3977)
