Aaron Adams discovered that the netfilter subsystem in the Linux kernel did
not properly handle the removal of stateful expressions in some situations,
leading to a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or execute arbitrary code.

Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM
implementation in the Linux kernel did not properly perform guest page
table updates in some situations. An attacker in a guest vm could possibly
use this to crash the host OS. (CVE-2022-1158)

Ziming Zhang discovered that the netfilter subsystem in the Linux kernel
did not properly validate sets with multiple ranged fields. A local
attacker could use this to cause a denial of service or execute arbitrary
code. (CVE-2022-1972)

It was discovered that the USB Gadget file system interface 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-2022-24958)

It was discovered that the EMS CAN/USB interface implementation in the
Linux kernel contained a double-free vulnerability when handling certain
error conditions. A local attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2022-28390)");
