CVE-2026-68241

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/i915/mst: limit DP MST ESI service loop<br /> <br /> The loop in intel_dp_check_mst_status() keeps servicing interrupts<br /> originating from the sink without bound. Add an upper bound to the new<br /> interrupts occurring during interrupt processing to not get stuck on<br /> potentially stuck sink devices. Use arbitrary 32 tries to clear incoming<br /> interrupts in one go.<br /> <br /> Discovered using AI-assisted static analysis confirmed by Intel Product<br /> Security.<br /> <br /> Note: The condition likely pre-dates the commit in the Fixes: tag, but<br /> this is about as far back as a backport has any chance of<br /> succeeding. Before that, the retry had a goto.<br /> <br /> (cherry picked from commit b4ea5272133059acb493cc36599071a9e852ec2e)
