USN-7381-1: Linux kernel (Low Latency) vulnerabilities
27 March 2025

Several security issues were fixed in the Linux kernel.

Releases

  • Ubuntu 24.04 LTS

Packages

  • linux-lowlatency-hwe-6.11 - Linux low latency kernel

Details
Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2025-0927)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

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

Ubuntu 24.04

  • linux-image-6.11.0-1011-lowlatency - 6.11.0-1011.12~24.04.1
  • linux-image-6.11.0-1011-lowlatency-64k - 6.11.0-1011.12~24.04.1
  • linux-image-lowlatency-64k-hwe-24.04 - 6.11.0-1011.12~24.04.1
  • linux-image-lowlatency-hwe-24.04 - 6.11.0-1011.12~24.04.1
    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.
