CVE-2026-31679

In the Linux kernel, the following vulnerability has been resolved: openvswitch: validate MPLS set/setmasked payload length validateset accepted OVSKEYATTRMPLS as variable-sized payload for SET/SETMASKED actions. In action handling, OVS expects fixed-size MPLS key data struct ovskeympls. Use the...

CVE-2026-31679

Summary: CVE-2026-31679 affects the Linux kernel openvswitch code. The vulnerability arises from improper validation of MPLS payload lengths in SET/SET_MASKED actions: openvswitch accepted OVS_KEY_ATTR_MPLS as a variable-sized payload, while action handling expects fixed-size MPLS data (struct ov...
