A race condition exists in the printing module of Huawei HarmonyOS, allowing a successful exploitation to disrupt service availability. The flaw pertains to concurrent access to shared resources in the print subsystem, which can cause the system to hang or crash when multiple print jobs are processed simultaneously.

Huawei HarmonyOS version 6.0.0 is affected. Devices running this operating system that utilize the built‑in printing functionality are at risk.

The vulnerability carries a CVSS score of 6.2, indicating moderate severity, and an EPSS score of less than 1%, suggesting a very low probability of exploitation at present. It is not listed in the CISA KEV catalog. The attack vector is inferred to be dependent on the ability to submit print jobs, potentially via local or network‑bound printing interfaces, but the exact exploitation path has not been publicly confirmed in the description.
