- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

A security issue was fixed in Linux kernel.

Software Description:
- linux: Linux kernel
- linux-lowlatency: Linux low latency kernel
- linux-lowlatency-hwe-6.8: Linux low latency kernel

Details:

A security issue was discovered in the Linux kernel.
An attacker could possibly use this to compromise the system.
This update corrects flaws in the following subsystems:
  - Media drivers;
(CVE-2024-53104)

Update instructions:

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

Ubuntu 24.04 LTS
  linux-image-6.8.0-55-generic    6.8.0-55.57
  linux-image-6.8.0-55-generic-64k  6.8.0-55.57
  linux-image-6.8.0-55-lowlatency  6.8.0-55.57.1
  linux-image-6.8.0-55-lowlatency-64k  6.8.0-55.57.1
  linux-image-generic             6.8.0-55.57
  linux-image-generic-64k         6.8.0-55.57
  linux-image-generic-lpae        6.8.0-55.57
  linux-image-kvm                 6.8.0-55.57
  linux-image-lowlatency          6.8.0-55.57.1
  linux-image-lowlatency-64k      6.8.0-55.57.1
  linux-image-virtual             6.8.0-55.57

Ubuntu 22.04 LTS
  linux-image-6.8.0-55-lowlatency  6.8.0-55.57.1~22.04.1
  linux-image-6.8.0-55-lowlatency-64k  6.8.0-55.57.1~22.04.1
  linux-image-lowlatency-64k-hwe-22.04  6.8.0-55.57.1~22.04.1
  linux-image-lowlatency-hwe-22.04  6.8.0-55.57.1~22.04.1

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.
