Summary

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)

It was discovered that the SCTP protocol implementation in the Linux kernel
did not properly verify VTAGs in some situations. A remote attacker could
possibly use this to cause a denial of service (connection disassociation).
(CVE-2021-3772)

Eric Biederman discovered that the cgroup process migration implementation
in the Linux kernel did not perform permission checks correctly in some
situations. A local attacker could possibly use this to gain administrative
privileges. (CVE-2021-4197)

Jann Horn discovered that the FUSE file system 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-2022-1011)

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)

Duoming Zhou discovered that the 6pack protocol implementation in the Linux
kernel did not handle detach events properly in some situations, leading to
a use-after-free vulnerability. A local attacker could use this to cause a
denial of service (system crash). (CVE-2022-1198)

It was discovered that the PF_KEYv2 implementation in the Linux kernel did
not properly initialize kernel memory in some situations. A local attacker
could use this to expose sensitive information (kernel memory).
(CVE-2022-1353)

It was discovered that the implementation of X.25 network protocols in the
Linux kernel did not terminate link layer sessions properly. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2022-1516)

Demi Marie Obenour and Simon Gaiser discovered that several Xen para-
virtualization device frontends did not properly restrict the access rights
of device backends. An attacker could possibly use a malicious Xen backend
to gain access to memory pages of a guest VM or cause a denial of service
in the guest. (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038,
CVE-2022-23039, CVE-2022-23040, CVE-2022-23041, CVE-2022-23042)

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 USB SR9700 ethernet device driver for the Linux
kernel did not properly validate the length of requests from the device. A
physically proximate attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2022-26966)

赵子轩 discovered that the 802.2 LLC type 2 driver in the Linux kernel did not
properly perform reference counting in some error conditions. A local
attacker could use this to cause a denial of service. (CVE-2022-28356)

It was discovered that the Microchip CAN BUS Analyzer interface
implementation in the Linux kernel did not properly handle certain error
conditions, leading to a double-free. A local attacker could possibly use
this to cause a denial of service (system crash). (CVE-2022-28389)

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)
