CVE-2025-31948

Local application denial of service

Published Nov 11, 2025 · Updated Nov 11, 2025

Improper input validation in Intel oneAPI Math Kernel Library before 2025.2 allows local users to interrupt applications. Intel identifies the flaw only as improper input validation and has not published the affected routine, input type, or invalid operation. A low-privilege authenticated user can trigger the condition without user interaction, causing an availability-only interruption in a Ring 3 application.
