CVE-2024-41018

Kernel compromise via unbounded NTFS log entry walk

Published Jul 29, 2024 · Updated Aug 5, 2026

Out-of-bounds access in Linux NTFS3 6.6.19 through 6.6.42, 6.7.7, and 6.8 allows local users to compromise the kernel. In log_replay, an unbounded ATTR_NAME_ENTRY walk trusts entry offsets and writes a pointer and length outside the duplicated open-attribute table. Exploitation requires mounting an attacker-crafted NTFS volume or image and can corrupt kernel memory or panic the system.
