CVE-2026-68242

A flaw was found in the Linux kernel's graphics subsystem (specifically drm/i915/gt). This vulnerability arises from an improper handling of memory allocation failures during graphics engine scheduling, which can lead to a null pointer dereference. A local attacker could exploit this issue to trigger a system crash, resulting in a Denial of Service (DoS).

This issue affects Intel i915 virtual engine creation. intel_context_put() before intel_context_init() on sched_engine allocation failure causes NULL dereference. Systems without Intel graphics are not affected.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the i915 module from loading. See https://access.redhat.com/solutions/41278 for instructions.
