CVE-2026-68274

A flaw was found in the Linux kernel's drm/xe/guc component. An incorrect calculation of the steered register list allocation size can lead to a buffer overflow. This allows an attacker to write past the allocated buffer, corrupting adjacent memory objects. This memory corruption can result in...

CVE-2026-68382

A flaw was found in the Linux kernel's drm/xe/guc module. This vulnerability arises from a race condition during the asynchronous destruction of the Graphics micro-controller GuC execution queues. If the device reference is released prematurely, it can lead to a deadlock within the Direct Renderi...

CVE-2026-68383

A flaw was found in the Linux kernel's drm/xe/guc component. The scheduler maintains a pointer to a timeline name, but this name is prematurely freed while other parts of the system, such as scheduler fences, can still reference it. This creates a use-after-free vulnerability, where the system...

EUVD-2026-55569

In the Linux kernel, the following vulnerability has been resolved: drm/xe/guc: Keep scheduler timeline name alive The scheduler keeps a pointer to the timeline name, but q-name is freed with the exec queue while scheduler fences can still reference it. Store the name in struct xegucexecqueue so ...

CVE-2026-68382 drm/xe/guc: Hold device ref until queue teardown completes

In the Linux kernel, the following vulnerability has been resolved: drm/xe/guc: Hold device ref until queue teardown completes GuC exec queue destruction can run asynchronously. If the final device put happens from a destroy worker, drmm cleanup can end up draining the same workqueue and deadlock...

CVE-2025-68326

The vulnerability is in the Linux kernel DRM XE GUC path. A missing stack_depot_init() call when CONFIG_DRM_XE_DEBUG_GUC is enabled caused NULL pointer dereferences in stack_depot_save_flags, triggering a crash on drm_sched_run_job_work. The issue was fixed by cherry-picking commit 64fdf496a6929a...
