CVE-2024-45781 (GCVE-0-2024-45781)

Vulnerability from cvelistv5 – Published: 2025-02-18 19:25 – Updated: 2026-01-29 18:19

Title

Grub2: fs/ufs: oob write in the heap

Summary

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.

Severity ?

6.7 (Medium)
