Service interruption via NMS privilege escalation
Published Jul 25, 2024 · Updated Aug 2, 2024
Privilege escalation in the NMS module in Huawei HarmonyOS and EMUI allows local users to interrupt service availability. The faulty NMS operation and attacker-controlled input that trigger the escalation have not been published by Huawei. Exploitation requires low privileges and local access with no user interaction; the exact form of the availability loss is undisclosed.
