USN-5416-1: Linux kernel (OEM) vulnerabilities
12 May 2022

Several security issues were fixed in the Linux kernel.
Releases

  o Ubuntu 20.04 LTS

Packages

  o linux-oem-5.14 - Linux kernel for OEM systems

Details

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 )

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 )

It was discovered that the 8 Devices USB2CAN 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-2022-28388 )

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 )

Update instructions

The problem can be corrected by updating your system to the following package
versions:

Ubuntu 20.04

  o linux-image-5.14.0-1036-oem - 5.14.0-1036.40
  o linux-image-oem-20.04c - 5.14.0.1036.33
  o linux-image-oem-20.04b - 5.14.0.1036.33
  o linux-image-oem-20.04d - 5.14.0.1036.33
  o linux-image-oem-20.04 - 5.14.0.1036.33

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
