Xiaomi has implemented a series of software updates for its HyperOS ecosystem, addressing security, connectivity, and device stability.

Initial updates focused on security patches to mitigate digital threats, specifically addressing critical vulnerabilities such as CVE-2026-007 in the Linux kernel. This flaw reportedly affected WiFi and mobile data connections, potentially allowing unauthorized file extraction.

Subsequent updates expanded to include global Bluetooth improvements for Xiaomi, Redmi, and POCO devices. These enhancements aimed to resolve audio stuttering, latency, and connection failures while optimizing energy efficiency. Additionally, firmware updates were released for the Xiaomi Watch 5 to improve notification stability and resolve system display errors.

In September 2026, Xiaomi released a major security update for its smartphones and tablets, addressing approximately 180 vulnerabilities across the operating system, kernel, and hardware components. These fixes target components from manufacturers including Qualcomm, MediaTek, Arm, and Unisoc, covering areas such as Android Runtime, Framework, and System modules. This rollout is linked to the deployment of HyperOS 4 and is being distributed through stable channels and open-beta programs for various models, including the MIX Flip 2, Xiaomi Pad 7S Pro, Xiaomi 15, and Xiaomi 15 Ultra.
