CVE-2026-64359
Description
A flaw was found in the Linux kernel's nilfs2 filesystem. This vulnerability occurs because user-supplied segment numbers are not properly validated before processing CLEAN_SEGMENTS ioctl requests. An attacker, by providing out-of-range segment numbers, can trigger excessive logging. This prolonged logging can cause the system to become unresponsive, leading to a Denial of Service (DoS) where legitimate operations are blocked.
