## Overview

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.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
