linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities

Published May 12, 2022 · Updated Sep 10, 2026

Summary

Jeremy Cline discovered a use-after-free in the nouveau graphics driver of
the Linux kernel during device removal. A privileged or physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2020-27820)

It was discovered that a race condition existed in the network scheduling
subsystem of 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-2021-39713)

It was discovered that the Parallel NFS (pNFS) implementation in the Linux
kernel did not properly perform bounds checking in some situations. An
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2021-4157)

It was discovered that the ST21NFCA NFC driver in the Linux kernel did not
properly validate the size of certain data in EVT_TRANSACTION events. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-26490)

It was discovered that the Xilinx USB2 device gadget driver in the Linux
kernel did not properly validate endpoint indices from the host. A
physically proximate attacker could possibly use this to cause a denial of
service (system crash). (CVE-2022-27223)

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)
