Details

In the Linux kernel, the following vulnerability has been resolved:

ext4: add EXT4_INODE_HAS_XATTR_SPACE macro in xattr.h

When adding an xattr to an inode, we must ensure that the inode_size is not less than EXT4_GOOD_OLD_INODE_SIZE + extra_isize + pad. Otherwise, the end position may be greater than the start position, resulting in UAF.
