CVE-2025-49682

Local privilege escalation via use-after-free

Published Jul 8, 2025 · Updated Feb 26, 2026

Use-after-free in Windows Media on affected Windows releases allows local users to elevate privileges through crafted media. Windows Media reuses an object after its memory has been freed, but Microsoft has not disclosed the responsible file, function, or object lifetime error. Exploitation requires low-privileged local access and user interaction, and successful exploitation grants higher Windows privileges.
