06 Oct 2023 — A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses. Se encontró una falla en Open vSwitch que permite que los paquetes de anuncios de vecinos ICMPv6 entre máquinas virtuales omitan las reglas de OpenFlow. Este problema puede permitir que un atac... • http://www.openwall.com/lists/oss-security/2024/02/08/4 • CWE-345: Insufficient Verification of Data Authenticity •

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. An update for redhat-release-virtualization-host and re... • https://bugzilla.redhat.com/show_bug.cgi?id=2137666 • CWE-670: Always-Incorrect Control Flow Implementation •

04 May 2022 — A flaw was found in the vhost library in DPDK. Function vhost_user_set_inflight_fd() does not validate `msg->payload.inflight.num_queues`, possibly causing out-of-bounds memory read/write. Any software using DPDK vhost library may crash as a result of this vulnerability. Se ha encontrado un fallo en la biblioteca vhost de DPDK. La función vhost_user_set_inflight_fd() no comprueba "msg-)payload.inflight.num_queues", causando posiblemente una lectura/escritura de memoria fuera de límites. • https://access.redhat.com/security/cve/CVE-2021-3839 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

20 Jan 2022 — A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments. Se ha encontrado una pérdida de memoria en Open vSwitch (OVS) durante el procesamiento de la fragmentación IP en el espacio de usuario. Un atacante podría usar este fallo para agotar potencialmente la memoria disponible al seguir enviando fragmentos de paquetes.

13 Nov 2019 — A flaw was found in all dpdk version 17.x.x before 17.11.8, 16.x.x before 16.11.10, 18.x.x before 18.11.4 and 19.x.x before 19.08.1 where a malicious master, or a container with access to vhost_user socket, can send specially crafted VRING_SET_NUM messages, resulting in a memory leak including file descriptors. This flaw could lead to a denial of service condition.
