CVE-2026-72361

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

drm/xe/hw_engine: Fix double-free of managed BO in error path

The error path in hw_engine_init() explicitly frees a BO allocated

with xe_managed_bo_create_pin_map() via xe_bo_unpin_map_no_vm().

Since the managed BO already has a devm cleanup action registered,

this causes a double-free when devm unwinds during probe failure.

Remove the explicit free and let devm handle it, consistent with

all other xe_managed_bo_create_pin_map() callers.

(cherry picked from commit e459a3bdeb117be496d7f229e2ea1f6c9fe4080b)

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
