Linux Kernel GuC Virtual Engine Request Handling Use-After-Free Vulnerability

A use-after-free vulnerability has been addressed in the Linux kernel's handling of requests for GuC virtual engines within the i915 graphics driver. This issue arose because references to i915_requests could be retained by userspace through sync_files or dmabufs, potentially leading to memory leaks. The vulnerability affected several versions of the Linux kernel.

Impact

The vulnerability could lead to a use-after-free condition, allowing for memory corruption or exploitation opportunities.

Remediation

Users can upgrade to the latest version of the Linux kernel to address this vulnerability.
