Several issues were found in the GRUB2 bootloader, which could result in crashes and potentially execution of arbitrary code. These could lead to bypass of UEFI Secure Boot on affected systems.

For Debian 11 bullseye, these problems have been fixed in version 2.06-3~deb11u7.

We recommend that you upgrade your grub2 packages.

For the detailed security status of grub2 please refer to its security tracker page at:
