Service interruption via concurrent database access
Published May 13, 2022 · Updated Aug 3, 2024
Concurrency flaw in the graphics acceleration service in Huawei HarmonyOS 2.0 and EMUI 12.0.0 allows remote attackers to interrupt the service. The service permits unsynchronized multi-threaded database access, allowing concurrent operations to place the service in an exceptional state. Huawei has not disclosed the database, triggering input, or whether the exception is a hang or crash; the published impact is limited to service disruption.
