Vulnerability Title
Grub2: fs/hfs: strcpy() using the volume name (fs/hfs.c:382)
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in the HFS filesystem. When reading an HFS volume's name at grub_fs_mount(), the HFS filesystem driver performs a strcpy() using the user-provided volume name as input without properly validating the volume name's length. This issue may read to a heap-based out-of-bounds writer, impacting grub's sensitive data integrity and eventually leading to a secure boot protection bypass.
