grub2: An integer overflow flaw was found in the BFS file system driver in grub2
CVE-2024-45779 is fixed in 25 products on 1 platform, first by SUSE-SU-2025:0586-1, released February 19, 2025. It is not reported as exploited. Patch Radar priority: Routine.
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.
