CVE-2025-31937

Authenticated denial of service via out-of-bounds read

Published Nov 11, 2025 · Updated Nov 11, 2025

Out-of-bounds read in Intel QuickAssist Technology Windows software before 2.6.0 allows local users to interrupt the system. A Ring 3 user application performs an out-of-bounds read, but Intel has not disclosed the affected routine, malformed input, or invalid read path. The attack requires an authenticated local user and high complexity without user interaction; Intel does not specify whether the interruption is a hang, crash, or reboot.
