- 7.1 HIGH — CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H
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]
