CVE-2023-35361

SYSTEM privilege escalation via kernel race condition

Published Jul 11, 2023 · Updated Jan 1, 2025

Race condition in the Windows kernel in Microsoft Windows allows local users to elevate privileges to SYSTEM through local execution. Microsoft identifies improper synchronization of a shared resource but has not disclosed the affected kernel routine or the competing operations. Exploitation requires low-privileged local access and winning a high-complexity race; successful exploitation grants complete control of the host.
