DoS vulnerability in the input device module. Impact: Successful exploitation of this vulnerability may affect availability.
AnalysisAI
Denial-of-service in Huawei HarmonyOS and EMUI's input device module allows a local unprivileged attacker to crash affected system components, impacting device availability. The CVSS scope change (S:C) indicates the flaw propagates availability impact beyond the vulnerable input module itself, potentially affecting higher-privileged or dependent subsystems. …
