CVE-2024-2182 is a vulnerability in OVN (Open Virtual Network) where insufficient validation of BFD (Bidirectional Forwarding Detection) packets can cause a denial of service condition. OVN provides virtual network abstractions complementing Open vSwitch capabilities. Red Hat has issued an important security advisory (RHSA-2024:4035) for Red Hat Enterprise Linux Fast Datapath 8, releasing updated ovn-2021 packages that fix this issue. The advisory includes packages for multiple CPU architectures and instructs users to apply the update after ensuring all previous errata are applied.

Potential Impact

The vulnerability allows an attacker to cause a denial of service by sending malformed BFD packets that are not properly validated by OVN.
