CVE-2026-68268

A flaw was found in the drm/xe component of the Linux kernel. Non-migratable faults requiring device memory (devmem) incorrectly suppress error codes, preventing them from being returned to higher layers of the system. This improper error handling could lead to unexpected system behavior or resource issues, potentially resulting in a denial of service.

This issue affects Intel Xe graphics with non-migratable faults requiring device memory. Error codes were squashed by jumping to a shared out label, masking -EACCES from upper layers. Systems without Intel Xe are not affected.
