UBUNTU-CVE-2026-68258: High severity ubuntu/linux vulnerability
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check bounds on CRIU restore queue type and mqd size We weren't checking whether the values provided in the private data in kfd CRIU restore were within bounds. For queue type, add a KFDQUEUETYPEMAX and ensure the provided type is less than it. For mqdsize, add new function mqdsizefromqueuetype and confirm that the provided mqdsize matches expectations. (cherry picked from commit f19d8086f6644083c913d70bfdeee20e1b6f46a5)
