Code execution via DSoftBus out-of-bounds write
Published Feb 2, 2024 · Updated Aug 22, 2024
Out-of-bounds write in DSoftBus in OpenHarmony 3.2.0 through 3.2.4 allows remote attackers on an adjacent network to execute code. The published record says DSoftBus writes beyond a buffer boundary but does not identify the function, destination buffer, or attacker-controlled field. No authentication or user interaction is required, but the attacker must share an adjacent network and satisfy a high-complexity condition that OpenHarmony has not described.

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.
- Affected versionversion=v3.2.0 <=v3.2.4
