Out-of-bounds read via unvalidated keymaster data
Published Oct 14, 2022 · Updated May 14, 2025
Out-of-bounds read in Huawei HarmonyOS 2.0, EMUI 11.0.1, and EMUI 12.0.0 allows attackers to read memory via crafted keymaster data. The HW_KEYMASTER module accepts read content without validating it, allowing crafted values to direct an access beyond the intended memory boundary. Public material does not identify the supplying interface or the specific data exposed by the out-of-bounds read.
