Local privilege escalation via WLAN object mishandling
Published Jun 9, 2020 · Updated Aug 4, 2024
Object-handling flaw in Microsoft Windows WLAN Service allows local users to execute code with elevated privileges via a crafted application. The wlansvc.dll service component mishandles objects in memory; Microsoft has not disclosed the specific incorrect memory operation. A user must already have local code-execution access, and successful exploitation can compromise confidentiality, integrity, and availability at elevated privilege.
