Description OSIDB Bzimport 2026-09-24 16:54:37 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amdkfd: fix UAF race in destroy_queue_cpsch

wait_on_destroy_queue() drops locks to wait for queue resume, allowing
a concurrent destroy to free the queue. Use is_being_destroyed flag to
serialize destruction.
