Service interruption via COPS packet decoding
Published Dec 28, 2024 · Updated Dec 31, 2024
Out-of-bounds reads in the COPS decoder in affected Huawei security products allow remote attackers to interrupt device service. The decoding function reads beyond packet bounds while processing a crafted incoming COPS packet. Reachability requires access to the affected network, and the documented consequence is service disruption without data disclosure or modification.
