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

drm/amdkfd: fix QID bit leak in pqm_create_queue()

When MES is enabled and amdgpu_amdkfd_alloc_kernel_mem() fails during the first queue creation for a process, pqm_create_queue() returns early via 'return retval' without going through the err_create_queue cleanup label.

This means clear_bit(*qid, pqm->queue_slot_bitmap) is never called, leaving the reserved QID bit permanently set in queue_slot_bitmap. Over time this leaks QID slots, potentially exhausting all available queue slots.

Fix this by replacing 'return retval' with 'goto err_allocate_pqn' so that clear_bit() is always called on the error path without touching the uninitialized pqn pointer.

AILIKFD-813

(cherry picked from commit a107f74c38edbb80d6ab64dcaeeb292c14e9779f)
