CVE-2026-90419 Details

Description

In the Linux kernel, the following vulnerability has been resolved: nilfs2: prevent out-of-bounds read in super root block parsing super-root inode metadata size is trusted before nilfs_read_inode_common(). Reject super-root inode sizes whose computed on-disk footprint exceeds the filesystem block size. This prevents malformed filesystem images from making nilfs_read_inode_common() read past the end of the super-root block. [ryusuke: clarify the commit title]
