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...

CVE-2026-68383

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-2026-68274

In the Linux kernel, the following vulnerability has been resolved: drm/xe/guc: Fix buffer overflow in steered register list allocation The size calculation for the steered register extarray uses only the geometry DSS mask gdssmask to determine the number of entries to allocate: total =...

CVE-2026-68382

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...
