Official description

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Check bounds in allocate_event_notification_slot The valid event ids go from 0 to KFD_SIGNAL_EVENT_LIMIT allocate_event_notification_slot has an option to specify an event id to allocate at, used by CRIU. We weren't checking the bounds on that value. Check them. v2: Lower bounds check is unecessary because of idr_alloc already rejecting negative numbers. Upper bounds check should be KFD_SIGNAL_EVENT_LIMIT since the signal mode mappings might not yet exist (cherry picked from commit 6853f1f6cbbeb3f53ebbbd7286536aeb2c5d5f50)
