GRUB (affected versions not specified)
Description
A Use-After-Free issue exists in GRUB's gettext module. This occurs because the gettext command remains registered in memory after its module is unloaded. Exploitation involves invoking the orphaned command, leading to access of an invalid memory location. This can cause GRUB to crash, resulting in a Denial of Service. A potential compromise of data integrity or confidentiality is possible.
