CVE-2023-53033

netfilter: nft_payload: incorrect arithmetics when fetching VLAN header bits

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

netfilter: nft_payload: incorrect arithmetics when fetching VLAN header bits

If the offset + length goes over the ethernet + vlan header, then the
length is adjusted to copy the bytes that are within the boundaries of
the vlan_ethhdr scratchpad area. The remaining bytes beyond ethernet +
vlan header are copied directly from the skbuff data area.

Fix incorrect arithmetic operator: subtract, not add, the size of the
vlan header in case of double-tagged packets to adjust the length
accordingly to address CVE-2023-0179.
