Summary

Some Huawei products have a buffer error vulnerability. An unauthenticated, remote attacker could send specific MPLS Echo Request messages to the target products. Due to insufficient input validation of some parameters in the messages, successful exploit may cause the device to reset.

Exploit prediction

0.97% chance of exploitation in the next 30 days, higher than 62% of all scored CVEs (FIRST EPSS, 2026-11-08).
