Title
Openvswitch: open vswitch: denial of service via malformed ftp epasv command
Summary
A flaw was found in Open vSwitch. When Open vSwitch is configured with a conntrack flow using FTP helpers over the userspace datapath, a remote attacker can send a specially crafted FTP stream with an EPASV command exceeding 255 characters. This heap access error can lead to a crash, resulting in a Denial of Service (DoS) for the affected system.

CVE-2026-5367 (GCVE-0-2026-5367)
Vulnerability from nvd – Published: 2026-04-24 12:25 – Updated: 2026-06-30 12:10

Title
Ovn: ovn: information disclosure via crafted dhcpv6 packets
Summary
A flaw was found in OVN (Open Virtual Network). A remote attacker, by sending crafted DHCPv6 (Dynamic Host Configuration Protocol for IPv6) SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the disclosure of sensitive information stored in heap memory, which is then returned to the attacker's virtual machine port.

CVE-2026-5265 (GCVE-0-2026-5265)
Vulnerability from nvd – Published: 2026-04-24 12:25 – Updated: 2026-06-17 22:00
VLAI
Title
Ovn: ovn: heap over-read in icmp error response generation
Summary
When generating an ICMP Destination Unreachable or Packet Too Big response, the handler copies a portion of the original packet into the ICMP error body using the IP header's self-declared total length (ip_tot_len for IPv4, ip6_plen for IPv6) without validating it against the actual packet buffer size. A VM can send a short packet with an inflated IP length field that triggers an ICMP error (e.g., by hitting a reject ACL), causing ovn-controller to read heap memory beyond the valid packet data and include it in the ICMP response sent back to the VM.

CVE-2024-11614 (GCVE-0-2024-11614)
Vulnerability from nvd – Published: 2024-12-18 08:30 – Updated: 2025-11-20 00:59

Title
Dpdk: denial of service from malicious guest on hypervisors using dpdk vhost library
Summary
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.

Title
Ovn: insufficient validation of bfd packets may lead to denial of service
Summary
A flaw was found in the Open Virtual Network (OVN). In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from inside unprivileged workloads, including virtual machines or containers, that can trigger a denial of service.

Title
Openvswitch: open vswitch: denial of service via malformed ftp epasv command
Summary
A flaw was found in Open vSwitch. When Open vSwitch is configured with a conntrack flow using FTP helpers over the userspace datapath, a remote attacker can send a specially crafted FTP stream with an EPASV command exceeding 255 characters. This heap access error can lead to a crash, resulting in a Denial of Service (DoS) for the affected system.

CVE-2026-5265 (GCVE-0-2026-5265)
Vulnerability from cvelistv5 – Published: 2026-04-24 12:25 – Updated: 2026-06-17 22:00
VLAI
Title
Ovn: ovn: heap over-read in icmp error response generation
Summary
When generating an ICMP Destination Unreachable or Packet Too Big response, the handler copies a portion of the original packet into the ICMP error body using the IP header's self-declared total length (ip_tot_len for IPv4, ip6_plen for IPv6) without validating it against the actual packet buffer size. A VM can send a short packet with an inflated IP length field that triggers an ICMP error (e.g., by hitting a reject ACL), causing ovn-controller to read heap memory beyond the valid packet data and include it in the ICMP response sent back to the VM.
Severity

CVE-2026-5367 (GCVE-0-2026-5367)

Title
Ovn: ovn: information disclosure via crafted dhcpv6 packets
Summary
A flaw was found in OVN (Open Virtual Network). A remote attacker, by sending crafted DHCPv6 (Dynamic Host Configuration Protocol for IPv6) SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the disclosure of sensitive information stored in heap memory, which is then returned to the attacker's virtual machine port.

CVE-2024-11614 (GCVE-0-2024-11614)
Vulnerability from cvelistv5 – Published: 2024-12-18 08:30 – Updated: 2025-11-20 00:59

Title
Dpdk: denial of service from malicious guest on hypervisors using dpdk vhost library
Summary
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.

Title
Ovn: insufficient validation of bfd packets may lead to denial of service
Summary
A flaw was found in the Open Virtual Network (OVN). In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from inside unprivileged workloads, including virtual machines or containers, that can trigger a denial of service.
