CVE-2024-45782
Date: March 3, 2025
A flaw was found in grub2. When reading a HFS volume's name at grub_fs_mount(), the HFS filesystem driver performs a strcpy() using the user provided volume name as input without proper validating the volume name's length. This may read to a heap based Out-of-bounds write, impacting on grub's sensitive data integrity and eventually leading to secure boot protection bypass.
