CVE-2026-83535

A flaw in openstack-network-exporter allows an adjacent network attacker to bypass basic authentication when Transport Layer Security (TLS) is omitted or misconfigured. Due to a fail-open design , an attacker can access sensitive Open vSwitch (OVS) and Open Virtual Network (OVN) dataplane metrics...

CVE-2026-83535: Observable Timing Discrepancy

A flaw was found in openstack-network-exporter. When an operator configures user authentication but omits or misconfigures Transport Layer Security TLS, the basic authentication mechanism is silently bypassed. This fail-open design allows an adjacent network attacker to access sensitive Open...

Astra Linux – Vulnerability in OVN

A flaw was discovered in OVN Open Virtual Network. A remote attacker, by sending crafted DHCPv6 Dynamic Host Configuration Protocol for IPv6 solicitation 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 le...

Astra Linux – Vulnerability in OVN

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 iptotlen for IPv4, ip6plen for IPv6, without validating it against the actual packet buffer siz...
