CVE-2024-45780

Date: March 3, 2025

A flaw was found in grub2. When reading tar files, grub2 allocates an internal buffer for the file name however it fails to properly verify the allocation against possible Integer Overflows. It's possible to cause the allocation length to overflow with a crafted tar file leading to a head Out-of-bounds write, as consequence an attacker may leverage this to eventually circumvent secure boot protections.
