USN-5358-1: Linux kernel vulnerabilities

Publication date

31 March 2022

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

Details

It was discovered that the network traffic control 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-2022-1055)

It was discovered that the IPsec implementation in the Linux kernel did not
properly allocate enough memory when performing ESP transformations,
leading to a heap-based buffer overflow. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-27666)

Update instructions

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

Learn more about how to get the fixes.

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.

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