medium 6.9
On affected EOS-based platforms, an attacker who controls a Border Gateway Protocol (BGP) peer can send a crafted BGP message over an established session with the Dynamic Path Selection (DPS) address family negotiated. This can cause the BGP process to terminate unexpectedly, resetting all BGP sessions and disrupting routing services until the process restarts.
