CVE-2026-28547

Service disruption via uninitialized pointer access

Published Mar 5, 2026 · Updated Mar 5, 2026

Uninitialized-pointer access in the scanning module in Huawei HarmonyOS 6.0.0 allows local users to disrupt service availability. The scanning module accesses a pointer whose value was never initialized, but Huawei has not disclosed the triggering input, function, or execution path. Exploitation requires local access, needs no prior privileges or user interaction, and can disrupt availability; the CNA also reports low confidentiality impact.
