How to fix?

Upgrade SLES:15.6 grub2-x86_64-xen to version 2.12-150600.8.18.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream grub2-x86_64-xen package and not the grub2-x86_64-xen package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure boot protections.
