Local privilege escalation via stack buffer overflow
Published Oct 10, 2023 · Updated Apr 14, 2025
Stack-based buffer overflow in Microsoft Windows Named Pipe File System allows local users to elevate privileges on affected systems. Microsoft maps the flaw to CWE-121 but has not disclosed the function, request field, or copying operation that overruns the stack buffer. Exploitation requires existing low-privilege local access; Microsoft has not specified the resulting privilege level.
