Am I affected, and how do I check?
The phones/tablets bulletin lists HarmonyOS 4.3.3, 4.3.1, 4.3.0, 4.2.0, 4.0.0 and EMUI 16.0.0, 15.0.0, 14.2.0, 14.0.0. The Vision bulletin lists HarmonyOS 4.3.0 only, so compare the version reported by the device against these lists.Source: consumer.huawei.com
What should I do about it?
The checked facts name no fixed version or patch, so no upgrade target can be confirmed here. Check Huawei's bulletin for the fix and the version that contains it.Source: consumer.huawei.com
Is it being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What if there's no patch?
