  "title": "nilfs2: prevent out-of-bounds read in super root block parsing",
  "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]",
