AI Analysis
Technical Summary
This vulnerability is a double free condition (CWE-415) found in the multi-mode input system component of Huawei HarmonyOS versions 5.1.0 and 6.0.0. A double free occurs when the system attempts to free the same memory location twice, which can lead to memory corruption and potentially cause a denial of service by affecting system availability. The CVSS 3.1 base score is 5.6, reflecting a medium severity with local attack vector, low attack complexity, requiring low privileges and user interaction, and impacting availability but not confidentiality or integrity. No vendor advisory or patch information is currently available.
Potential Impact
Successful exploitation may result in reduced availability of the affected HarmonyOS system due to memory corruption caused by the double free condition. There is no indication of confidentiality or integrity impact. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should exercise caution with untrusted input to the multi-mode input system and apply any recommended security best practices from Huawei. Monitor vendor channels for updates.
