Memory exposure via out-of-bounds heap read
Published Sep 16, 2022 · Updated Aug 4, 2024
Out-of-bounds heap read in Huawei EMUI 12.0.0 allows attackers to access memory outside a heap buffer via unspecified vectors. Huawei identifies HW_KEYMASTER as the affected module but has not published the input, function, or bounds-checking error that triggers the read. NVD assesses network reachability without authentication or user interaction, while Huawei bounds the stated consequence to out-of-bounds access.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
