linux, linux-aws, linux-aws-hwe, linux-dell300x, linux-hwe, linux-kvm, linux-oracle, linux-raspi2, linux-snapdragon vulnerabilities

Published Nov 16, 2022 · Updated Oct 22, 2026

Summary

It was discovered that a race condition existed in the instruction emulator
of the Linux kernel on Arm 64-bit systems. A local attacker could use this
to cause a denial of service (system crash). (CVE-2022-20422)

It was discovered that the KVM implementation in the Linux kernel did not
properly handle virtual CPUs without APICs in certain situations. A local
attacker could possibly use this to cause a denial of service (host system
crash). (CVE-2022-2153)

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. (CVE-2022-2978)

Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in
the Linux kernel. A local attacker could use this to cause a denial of
service (system crash) or possibly expose sensitive information (kernel
memory). (CVE-2022-3028)

It was discovered that the IDT 77252 ATM PCI device driver in the Linux
kernel did not properly remove any pending timers during device exit,
resulting in a use-after-free vulnerability. A local attacker could
possibly use this to cause a denial of service (system crash) or execute
arbitrary code. (CVE-2022-3635)

It was discovered that the Netlink Transformation (XFRM) subsystem in the
Linux kernel contained a reference counting error. A local attacker could
use this to cause a denial of service (system crash). (CVE-2022-36879)

Xingyuan Mo and Gengjia Chen discovered that the Promise SuperTrak EX
storage controller driver in the Linux kernel did not properly handle
certain structures. A local attacker could potentially use this to expose
sensitive information (kernel memory). (CVE-2022-40768)
