What is CVE-2026-97519?
CVE-2026-97519 is a vulnerability in Linux, published on 24 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix null pointer dereference in devcoredump cleanup
In xe_devcoredump_snapshot_free(), ss->gt may be NULL when the snapshot was never fully populated (e.g., when cleanup is triggered without a prior capture). Guard the xe_guc_capture_put_matched_nodes() call with IS_ERR_OR_NULL() to prevent a null dereference.
In xe_devcoredump_free(), the deferred work is only queued when a coredump is captured, so guard cancel_work_sync() with a check on coredump->captured.
