Local code execution via undisclosed buffer bounds flaw
Published Oct 28, 2021 · Updated Aug 3, 2024
Out-of-bounds memory access in Huawei HarmonyOS 2.0 allows local users to execute arbitrary code through a vulnerable component. Huawei has not identified the affected component or disclosed the malformed input and bounds-checking error that trigger the access. Exploitation requires local low-privileged access but no user interaction; successful exploitation runs attacker-controlled code in the affected context.
