https://notcve.org/view.php?id=CVE-2023-1668
10 Apr 2023 — A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.

https://notcve.org/view.php?id=CVE-2022-32166
28 Sep 2022 — In ovs versions v0.90.0 through v2.5.0 are vulnerable to heap buffer over-read in flow.c. An unsafe comparison of “minimasks” function could lead access to an unmapped region of memory. This vulnerability is capable of crashing the software, memory modification, and possible remote execution. ovs versiones v0.90.0 hasta v2.5.0, son vulnerables a una lectura excesiva del buffer de la pila en el archivo flow.c. Una comparación no segura de la función "minimasks" podría conllevar a un acceso a una región de me... • https://github.com/cloudbase/ovs/commit/2ed6505555cdcb46f9b1f0329d1491b75290fc73 • CWE-125: Out-of-bounds Read •
