netfilter: nf_tables: missing sanitization in data from userspace Do not assume userspace always sends us NFT_DATA_VALUE for bitwise and cmp expressions. Although NFT_DATA_VERDICT does not make any sense, it is still possible to handcraft a netlink message using this incorrect data type. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
