In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check bounds on allocate_doorbell
allocated_doorbell has an option to set the doorbell id
to a specific value (used by CRIU). This value was not
bounds checked.
Check to confirm it's less than KFD_MAX_NUM_OF_QUEUES_PER_PROCESS.
