Description

A flaw was found in the nilfs2 filesystem implementation within the Linux kernel. This vulnerability occurs due to insufficient validation of super-root inode metadata size before parsing. A local attacker could craft a malicious filesystem image that, when processed, causes an out-of-bounds read past the end of the super-root block. This could lead to information disclosure or a denial of service.
