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)
A flaw was found in the Linux kernel's `drm/amdkfd` component. When a process attempts to create its first queue, a failure in memory allocation can cause the `pqm_create_queue()` function to exit prematurely without releasing a reserved Queue ID (QID) bit. This leads to a permanent leak of QID slots. Over time, this resource exhaustion can prevent new queues from being created, resulting in a Denial of Service (DoS) for affected systems.
