Technical details

An incomplete cleanup vulnerability in the rpd process fails to properly clean up resources when processing BGP MVPN (Multicast VPN) updates, specifically when inter-region segmented VRF with 'protocols mvpn inter-region-template' is configured. A configured MVPN neighbor can send a malicious BGP MVPN update to trigger an uncontrolled crash (denial of service). The vulnerability requires the specific MVPN configuration and BGP session access to exploit.
