Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the drm/i915 subsystem related to handling requests for GuC virtual engines. Specifically, references to
i915 requests could be held indefinitely across different processes via sync file or dmabuf, potentially leading to memory leaks. To address this, the kernel attempts to avoid retaining references to requests after their completion and introduces a new bit in rq->execution mask to identify virtual engines. This change aims to prevent a use-after-free condition.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
