CVE-2024-55511Public exploit

System crash or privilege escalation via crafted executable

Published Jan 16, 2025 · Updated Feb 5, 2025

Null pointer dereference in Macrium Reflect before 8.1.8017 allows local users to crash Windows or elevate privileges. A specially crafted executable reaches an undisclosed code path that dereferences a null pointer; public sources do not identify the affected file, function, or driver. Low-privileged local access and no user interaction are required, and successful exploitation can halt the system or gain higher privileges.
