CVE-2024-58094

Kernel crash via read-only JFS truncation

Published Apr 16, 2025 · Updated Sep 2, 2026

A JFS truncation flaw in Linux 2.6.12 through 6.14.1 allows local users to crash the kernel through writes to a read-only filesystem. jfs_truncate_nolock continues into txEnd after the JFS log has been torn down, causing a null log dereference instead of stopping modification. Triggering the path requires a writable file descriptor retained across a forced read-only remount and subsequent write or truncate activity.
