Security Advisory
CVE-2024-45781
CVE vulnerability detail — eXtreme Datacenter Security Operations
Description
A flaw was found in grub2. When reading a symbolic links 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.
