Summary

A flaw has been identified in the GRUB2 bootloader's command/gpg functionality. When modules are unloaded, any hooks they created may not be removed properly. This can lead to a use-after-free condition, which, if successfully exploited, may allow an attacker to execute arbitrary code. This capability can potentially enable the attacker to bypass secure boot safeguards, thereby undermining system integrity.
