Description

A null pointer dereference vulnerability in Macrium Reflect prior to 8.1.8017 allows a local attacker to cause a system crash or potentially elevate their privileges via executing a specially crafted executable.

Security Summary

CVE-2024-55511 is a null pointer dereference vulnerability (CWE-476) in Macrium Reflect versions prior to 8.1.8017. Published on 2025-01-16, it carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The flaw arises from improper handling of a null pointer when executing a specially crafted executable.
