How to fix?

Upgrade Minimos:latest linux-virt-doc to version 6.12.22-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-virt-doc package and not the linux-virt-doc package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: NULL-check BO's backing store when determining GFX12 PTE flags

PRT BOs may not have any backing store, so bo->tbo.resource will be NULL. Check for that before dereferencing.

(cherry picked from commit 3e3fcd29b505cebed659311337ea03b7698767fc)
