Описание

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

openvswitch: validate MPLS set/set_masked payload length

validate_set() accepted OVS_KEY_ATTR_MPLS as variable-sized payload for SET/SET_MASKED actions. In action handling, OVS expects fixed-size MPLS key data (struct ovs_key_mpls).

Use the already normalized key_len (masked case included) and reject non-matching MPLS action key sizes.

Reject invalid MPLS action payload lengths early.
