Local buffer information disclosure via uninitialized resource
Published Nov 20, 2023 · Updated Aug 7, 2024
Use of uninitialized resource in OpenHarmony OpenHarmony v3.2.2 and earlier allows local attackers to read sensitive buffer information. The cert manager accesses a resource before initialization, exposing residual buffer contents to the caller. Exploitation requires local execution on an OpenHarmony device; the record reports confidentiality impact without integrity or availability effects.
