CVE-2024-41014

Kernel memory disclosure via undersized XFS log operation

Published Jul 29, 2024 · Updated Aug 5, 2026

Out-of-bounds read in XFS log recovery in affected Linux kernels allows attackers to disclose kernel memory via a crafted image. xlog_recover_process_data fails to verify that the remaining log-record buffer can hold the fixed xlog_op_header fields before reading them. Exploitation requires a victim or automounter to mount the malformed filesystem; the read can expose adjacent heap bytes in kernel logs or crash the mounting system.
