Xiaomi has started distributing the October 2026 security patch to 14 Xiaomi, REDMI, and POCO device entries across China and the EEA. The first recorded builds are dated October 1 and include software versions from both HyperOS 3 and HyperOS 4.
The rollout covers flagship phones, upcoming models listed in the firmware database, and a tablet. However, the available records do not confirm that every listed build is publicly available or that all regions have received the update.
October 2026 Patch Reaches Xiaomi and POCO Flagships
The October patch has appeared in firmware records for several flagship models in China, including the Xiaomi 17 series, REDMI K90 Pro Max, and POCO F8 Ultra.
The listed builds use the OS4.0.2.0 version prefix. The records also include the Xiaomi Pad 8 Pro, extending the list beyond smartphones.
EEA Builds Include POCO M7 Plus and REDMI 15
Three additional device entries use the same EEA firmware build, OS3.0.303.0.WOUEUXM. They are listed under the POCO M7 Plus, POCO M8s, and REDMI 15.
Since all three entries share the same build number, the records alone do not establish whether their firmware packages are identical across every hardware configuration. Users should select the package that matches their exact device and region.

Check the Firmware for Your Region
Users can check the lists Xiaomi firmware by device and region. The Security Patch Tracker can also help track patch availability.
The listed dates indicate when these builds were recorded, not necessarily when every user received an OTA notification. Xiaomi has not provided a changelog in the supplied information, so specific bug fixes or security vulnerabilities cannot be confirmed from these records alone.
