CVE-2024-57262

Code execution via wrapped symlink allocation

Published Feb 19, 2025 · Updated Feb 19, 2025

Memory corruption in Pengutronix barebox before 2025.01.0 allows physically proximate attackers to execute code via a crafted ext4 filesystem. The ext4fs_read_symlink function adds one to an untrusted 32-bit inode size before passing it to zalloc; 0xffffffff wraps to zero, so later symlink copying overwrites memory. Exploitation requires control of filesystem data parsed during boot and can bypass a verified-boot chain.
