CVE-2024-31177Network attack vector

Unauthenticated controller interruption via malformed OpenFlow message

Published Sep 18, 2024 · Updated Sep 18, 2024

Out-of-bounds read in Open Networking Foundation libfluid 0.1.0 allows remote attackers to interrupt a controller via OpenFlow traffic. The flaw occurs in TableFeaturePropActions::unpack, but Nozomi has not disclosed the malformed field or specific missing bounds check that permits the read. Exploitation requires network reachability to a controller or driver using the affected parser and can stop the target component.
