The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error when reading a volume's name within the grub_fs_mount() function in HFS filesystem driver. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

Install updates from vendor's website.
