CVE-2026-28544

Availability disruption via printing-module race condition

Published Mar 5, 2026 · Updated Mar 5, 2026

Race condition in the printing module in Huawei HarmonyOS 6.0.0 allows local users to disrupt system availability. Huawei identifies the locus only as the printing module and has not published the shared resource, unsynchronized operation, trigger, or resulting failure mode. Exploitation is local and high complexity; the published material does not distinguish a hang, crash, or broader service interruption.
