Debian LTS Advisory DLA-3190-1 [email protected]
https://www.debian.org/lts/security/ Steve McIntyre

Package : grub2
Version : 2.06-3~deb10u2
CVE ID : CVE-2022-2601 CVE-2022-3775
Several issues were found in GRUB2's font handling code, which could
result in crashes and potentially execution of arbitrary code. These
could lead to by-pass of UEFI Secure Boot on affected systems.
Further, issues were found in image loading that could potentially
lead to memory overflows.
For Debian 10 buster, these problems have been fixed in version
2.06-3~deb10u2.
We recommend that you upgrade your grub2 packages.
