AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The vendor (Ubuntu) has released updated kernel packages that include the fix. Users should update to the fixed kernel versions to mitigate this vulnerability.
Description
A vulnerability in the Linux kernel's drm/xe component allowed an array of VM binds to potentially evict other buffer objects within the same virtual memory, leading to NULL pointer dereferences during the bind pipeline. This issue has been resolved by clearing the allow_res_evict flag in the xe_bo_validate call. The fix is included in updated Linux kernel versions. This vulnerability was addressed as part of a broader Linux kernel security update covering multiple subsystems.
