Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.04 LTS
linux-image-6.8.0-2049-raspi-realtime 6.8.0-2049.50
Available with Ubuntu Pro
linux-image-raspi-realtime 6.8.0-2049.50
Available with Ubuntu Pro
linux-image-raspi-realtime-6.8 6.8.0-2049.50
Available with Ubuntu Pro
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.

CVE-2026-46266, CVE-2026-46289, CVE-2026-46316, CVE-2026-46325)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.04 LTS
linux-image-6.17.0-1026-nvidia 6.17.0-1026.26
linux-image-6.17.0-1026-nvidia-64k 6.17.0-1026.26
linux-image-nvidia-6.17 6.17.0-1026.26
linux-image-nvidia-64k-6.17 6.17.0-1026.26
linux-image-nvidia-64k-hwe-24.04 6.17.0-1026.26
linux-image-nvidia-hwe-24.04 6.17.0-1026.26
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.

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 26.04 LTS
linux-image-7.0.0-1013-nvidia 7.0.0-1013.13
linux-image-7.0.0-1013-nvidia-64k 7.0.0-1013.13
linux-image-nvidia 7.0.0-1013.13
linux-image-nvidia-64k 7.0.0-1013.13
linux-image-nvidia-64k-7.0 7.0.0-1013.13
linux-image-nvidia-7.0 7.0.0-1013.13
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.
