NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by Centos.

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.
