CVE-2021-37060Network attack vector

Heap-address disclosure via improper SAMGR input validation

Published Dec 7, 2021 · Updated Aug 4, 2024

Improper input validation in SAMGR in Huawei HarmonyOS 2.0 allows remote attackers to disclose SAMGR heap addresses via unspecified input. Huawei identifies SAMGR as the affected locus but does not disclose which input is malformed or how its validation permits the disclosure. Network access without authentication is sufficient, and the documented consequence is limited to exposing heap addresses.
