On systems running Arista EOS with Open Shortest Path First version 3 (OSPFv3) configured, a specially crafted packet can lead to excessive CPU usage in the OSPFv3 process. This may cause the OSPFv3 process to restart, interrupting routes on the switch and potentially impacting network stability. While Arista discovered this issue through internal testing and reports no evidence of exploitation in the wild, it poses a risk to operational efficiency and network reliability.
