Doc Text:
A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a programming error where the gettext command remains registered in memory after its module is unloaded. An attacker can exploit this condition by invoking the orphaned command, causing the application to access a memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded.

Description OSIDB Bzimport 2025-11-12 21:21:16 UTC
The gettext command is registered in the gettext module during load. However, the command is not unregistered at the module unload. So, this may lead to use-after-free issue when the gettext command is invoked after the gettext module unload.
