CVE-2021-37042Network attack vector

Unauthenticated memory disclosure via improper verification

Published Dec 7, 2021 · Updated Aug 4, 2024

Out-of-bounds read in Huawei EMUI 10.1.0, 10.1.1, 11.0.0, and 11.0.1 allows remote attackers to read memory via unspecified vectors. Huawei has not published the affected component, input path, or verification operation that permits the read beyond an intended buffer. The published network vector requires neither authentication nor user interaction; confidentiality and availability are affected, while integrity is not.
