SYSTEM privilege escalation via heap buffer overflow
Published Dec 10, 2024 · Updated Jun 9, 2026
Heap-based buffer overflow in Microsoft Windows Task Scheduler allows local users with low privileges to gain SYSTEM privileges. Microsoft has not disclosed the affected Task Scheduler routine, attacker-controlled input, or unchecked operation that overruns heap memory. Exploitation requires local low-privilege access and no user interaction; success grants complete control within the affected Windows host.
