Xiaomi has begun rolling out the September 2026 security patch update to numerous devices across its portfolio of brands. This one fixes a massive list of critical vulnerabilities across the Android framework, system architecture, and vendor-specific hardware components, and must therefore be installed as soon as you receive the update.

The latest security patch is arriving as part of the larger HyperOS 4 release, which is primarily rolling out in China. Some global models have also recently started receiving the update as part of the open beta release. Soon, the September security update will also start rolling out to HyperOS 3 devices.

Go to Settings > About phone, then tap the HyperOS logo to check for updates manually if the update notification hasn’t arrived yet. As always, the latest rollout follows a staged manner and hence may take additional time to reach all users.

What’s inside the September 2026 security patch?

This is a massive security release that patches 180 vulnerabilities across the Android ecosystem. Not all of those may apply to Xiaomi devices, but that’s still a pretty major release compared to recent security patches.

According to Google, the September 2026 security patch resolves 95 vulnerabilities in the core system and framework. The most critical fix resolves a security flaw in the system component that allows for Remote Code Execution (RCE). This flaw requires zero additional privileges and no user interaction to exploit.

The additional 85 security fixes target hardware-specific components. This covers critical kernel vulnerabilities, as well as driver patches for Qualcomm, Arm, MediaTek, Imagination Technologies, and Uisoc components.

Even if a security release isn’t as big as this one, it’s always best to have the latest security patch installed on your device.
