CVE-2021-37037

Device restart via invalid address access

Published Dec 8, 2021 · Updated Aug 4, 2024

Invalid address access in EMUI 11.0.0 and HarmonyOS 2.0 allows attackers to restart devices via unspecified vectors. Huawei identifies the affected locus only as invalid address access in smartphone system software and does not publish the triggering component or operation on untrusted input. The advisory does not state required privileges, user interaction, configuration, or network position, so the bounded consequence is device restart without disclosed confidentiality or integrity impact.
