Local information disclosure via DSoftBus out-of-bounds read
Published Feb 2, 2024 · Updated Aug 2, 2024
An out-of-bounds read in OpenHarmony DSoftBus 3.2.0 through 3.2.4 allows local users to disclose memory contents via unspecified vectors. OpenHarmony identifies DSoftBus as the affected component but has not published the specific parsing path, buffer, or missing bounds check that permits the read. Local execution is required, attack complexity is high under the CNA assessment, and the reported consequence is limited to information disclosure.

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
