23 Jan 2025 — A flaw was found in the Open Virtual Network (OVN). Specially crafted UDP packets may bypass egress access control lists (ACLs) in OVN installations configured with a logical switch with DNS records set on it and if the same switch has any egress ACLs configured. This issue can lead to unauthorized access to virtual machines and containers running on the OVN network. Marius Berntsberg, Trygve Vea, Tore Anderson, Rodolfo Alonso, Jay Faulkner, and Brian Haley discovered that OVN incorrectly handled certain cr... • https://access.redhat.com/security/cve/CVE-2025-0650 • CWE-284: Improper Access Control •

18 Dec 2024 — An out-of-bounds read vulnerability was found in DPDK's Vhost library checksum offload feature. This issue enables an untrusted or compromised guest to crash the hypervisor's vSwitch by forging Virtio descriptors to cause out-of-bounds reads. This flaw allows an attacker with a malicious VM using a virtio driver to cause the vhost-user side to crash by sending a packet with a Tx checksum offload request and an invalid csum_start offset. An update for dpdk is now available for Red Hat Enterprise Linux 8.6 Ad... • https://access.redhat.com/security/cve/CVE-2024-11614 • CWE-125: Out-of-bounds Read •

26 Nov 2024 — A log spoofing flaw was found in the Tuned package due to improper sanitization of some API arguments. This flaw allows an attacker to pass a controlled sequence of characters; newlines can be inserted into the log. Instead of the 'evil' the attacker could mimic a valid TuneD log line and trick the administrator. The quotes '' are usually used in TuneD logs citing raw user input, so there will always be the ' character ending the spoofed input, and the administrator can easily overlook this. This logged str... • https://access.redhat.com/errata/RHSA-2024:10381 • CWE-20: Improper Input Validation •

26 Nov 2024 — A script injection vulnerability was identified in the Tuned package. The `instance_create()` D-Bus function can be called by locally logged-in users without authentication. This flaw allows a local non-privileged user to execute a D-Bus call with `script_pre` or `script_post` options that permit arbitrary scripts with their absolute paths to be passed. These user or attacker-controlled executable scripts or programs could then be executed by Tuned with root privileges that could allow attackers to local pr... • https://access.redhat.com/errata/RHSA-2024:10384 • CWE-269: Improper Privilege Management •

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.

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.
