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. |
