CVE-2026-68263

CVE-2026-68263: In the Linux kernel DRM/imagination path, a double call to drm_sched_entity_fini() was fixed. The issue arose when drm_sched_entity_destroy() invoked drm_sched_entity_fini() from pvr_context_kill_queues() and later again during pvr_queue_destroy(), causing a refcount underflow/use...

CVE-2026-68259

CVE-2026-68259 affects the Linux kernel's DRM/amdkfd path, specifically allocate_event_notification_slot. The vulnerability arises from not validating the upper bound of user-supplied event IDs used by CRIU; valid IDs are 0 to KFD_SIGNAL_EVENT_LIMIT. The fix adds bounds checks, ensuring the upper...

CVE-2026-68258

The CVE-2026-68258 issue affects the Linux kernel DRM/AMDKFD component, where CRIU restore data for KFD was not validated against bounds. The fix introduces a KFD_QUEUE_TYPE_MAX bound and ensures the provided queue type is less than it, and adds mqd_size_from_queue_type to validate the mqd_size a...
