SYSTEM privilege escalation via out-of-bounds read
Published Dec 10, 2024 · Updated Jun 9, 2026
An out-of-bounds read in Microsoft Windows WwanSvc allows physically proximate attackers with low privileges to gain SYSTEM privileges. Microsoft identifies the weakness but has not published the affected function, buffer, or input that crosses its boundary. Exploitation requires physical access and existing low privileges; success grants SYSTEM-level control.
