Local privilege escalation via shared-resource race
Published Jul 14, 2026 · Updated Jul 14, 2026
Race condition in Windows Media on Microsoft Windows 11 24H2, 25H2, and 26H1 allows local users to elevate privileges. Microsoft identifies unsynchronized concurrent access to a shared resource and a resulting use-after-free, but does not disclose the affected object, function, or operation. Exploitation requires an authenticated local user; success grants elevated privileges, while the published record does not identify the resulting privilege level.
