Service confidentiality impact via out-of-bounds write
Published Feb 6, 2026 · Updated Feb 6, 2026
Out-of-bounds write in Huawei's file system module in HarmonyOS 4.2.0 and EMUI 14.2.0 allows attackers to affect service confidentiality. Huawei identifies the module but has not disclosed the vulnerable locus, the input that reaches it, or how the write crosses a buffer boundary. Exploitation requires local access, high attack complexity, and user interaction, with no prior privileges, and affects confidentiality, integrity, and availability.
