CVE-2024-45779
6.0 · MEDIUMOverview
CVE-2024-45779 is a medium-severity vulnerability affecting gnu grub2. It was published on March 3, 2025 and has a CVSS 3.1 base score of 6.0 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.0, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
An integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a heap of bounds read. As a consequence, sensitive data may be leaked, or grub2 will crash.
Remediation
Check the references section for vendor advisories and patches from gnu. Update grub2 to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
