CVE-2023-52981

A flaw was found in the Linux kernel's Intel i915 graphics driver. An improper reference counting issue occurs during error capture and debugging operations when managing graphics request objects. A local user could exploit this vulnerability to cause a kernel crash, resulting in a Denial of Service (DoS).

This vulnerability is rated as Low severity because exploitation requires local system access on systems utilizing Intel GPU hardware, with the impact limited to a kernel crash resulting in denial of service. Typical Red Hat Enterprise Linux deployments operate headlessly or lack active Intel display controllers, significantly reducing practical exposure. Additionally, triggering the flawed reference tracking requires GPU error capture or administrative debugfs interactions, which are restricted under standard security profiles.
