Local privilege escalation via undisclosed heap overflow
Published Mar 12, 2024 · Updated May 3, 2025
Heap-based buffer overflow in Microsoft OMI before 1.8.1-0 allows local users to elevate privileges through an undisclosed vector. Microsoft identifies heap memory corruption but has not disclosed the affected function, attacker-controlled input, or overwrite operation. Low-privilege local access is required, and successful exploitation grants elevated control on the affected host.
