It was discovered that the Linux kernel did not properly restrict access to
the kernel debugger when booted in secure boot environments. A privileged
attacker could use this to bypass UEFI Secure Boot restrictions.
(CVE-2022-21499)
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.
(CVE-2022-1966)
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)
