What is CVE-2025-1125?

The GRUB bootloader's HFS filesystem module contains a security issue where it fails to adequately check for integer overflows during buffer size calculations using metadata from the filesystem. This flaw can be exploited by manipulating the filesystem to trigger an overflow, potentially allowing attackers to execute arbitrary code. Such exploitation could undermine secure boot mechanisms and lead to serious compromises of system integrity.
