CVE-2024-45781: Red Hat Enterprise Linux 10

Medium severity, CVSS 6.7. EPSS: 0.3% chance of exploitation in the next 30 days.

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.
