Local privilege escalation through undisclosed kernel flaw
Published Feb 25, 2021 · Updated Aug 3, 2024
Privilege escalation in affected Microsoft Windows 10 and Windows Server releases allows local users to gain elevated privileges. Microsoft identifies the Windows kernel as the affected component but has not disclosed the faulty operation or attacker-controlled input. Exploitation requires low-privileged local access and can grant control over protected data and system operation.
