CVE-2026-74448
Detail
Received This CVE record has recently been published to the CVE List and has been included within the NVD dataset.
Description
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.
