Spanning Tree 1: DOS attack sending conf BPDUs root@kitploit: Let's send some conf BPDUs claiming be root!!! By sending continously conf BPDU with root pathcost 0, randomly generated bridge id and therefore the same root id, and some default values for other fields, we try to annoy the switches...

CVE-2026-72389

A flaw was found in the Linux kernel's bridge Spanning Tree Protocol STP module. A missing check in the brtopologychangedetection function allows a topology change timer to be armed while a bridge is administratively down. This can be exploited by an attacker to trigger a use-after-free...
