CVE-2024-45779 (GCVE-0-2024-45779)

Vulnerability from cvelistv5 – Published: 2025-03-03 14:25 – Updated: 2025-11-14 01:33
VLAI?
Summary
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.
Severity ?
