Privilege elevation through undisclosed WLAN Service flaw
Published Jan 12, 2021 · Updated Nov 19, 2024
Elevation of privilege in the Windows WLAN Service on affected Windows releases allows local users to gain higher privileges. Microsoft has not disclosed the vulnerable code path or the incorrect operation the WLAN Service performs on attacker-controlled input. The published assessment requires low privileges and physical access, but does not identify the resulting privilege level or a safe trigger.
