USN-8095-1: Linux kernel vulnerabilities

Publication date

16 March 2026

Overview

Several security issues were fixed in the Linux kernel.

Releases

Packages

Details

Qualys discovered that several vulnerabilities existed in the AppArmor
Linux kernel Security Module (LSM). An unprivileged local attacker could
use these issues to load, replace, and remove arbitrary AppArmor profiles
causing denial of service, exposure of sensitive information (kernel
memory), local privilege escalation, or possibly escape a container.
(LP: #2143853)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:

  • ARM64 architecture;
  • MIPS architecture;
  • Nios II architecture;
  • PA-RISC architecture;
  • RISC-V architecture;
  • S390 architecture;
  • Sun Sparc architecture;
  • User-Mode Linux (UML);
  • x86 architecture;
  • Xtensa architecture;
  • Block layer subsystem;
  • Cryptographic API;
  • Compute Acceleration...

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:
