(CVE-2025-38083, CVE-2025-37797)

Update instructions:

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

Ubuntu 24.04 LTS
  linux-image-6.8.0-1032-raspi    6.8.0-1032.36
  linux-image-raspi               6.8.0-1032.36
  linux-image-raspi-6.8           6.8.0-1032.36

Ubuntu 22.04 LTS
  linux-image-6.8.0-1034-gcp      6.8.0-1034.36~22.04.2
  linux-image-6.8.0-1034-gcp-64k  6.8.0-1034.36~22.04.2
  linux-image-gcp                 6.8.0-1034.36~22.04.2
  linux-image-gcp-6.8             6.8.0-1034.36~22.04.2
  linux-image-gcp-64k             6.8.0-1034.36~22.04.2
  linux-image-gcp-64k-6.8         6.8.0-1034.36~22.04.2

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.
