MEDIUMRed Hat Enterprise Linux 10 - Heap Out-of-Bounds Write in GRUB2 UFS Symbolic Link Handling
Title source: llmDescription
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.
