CVE-2021-22482Network attack vector

Unauthenticated invalid-data transmission via uninitialized variable

Published Oct 28, 2021 · Updated Aug 3, 2024

Uninitialized-variable use in Huawei EMUI 11.0.0 allows remote attackers to transmit invalid data via unspecified network input. Huawei has not published the affected component, the variable, or the operation that consumes its uninitialized value. The modeled gate is unauthenticated network access, while the only documented consequence is transmission of invalid data.
