CVE-2026-5367

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...
