Emir BardakçıThe Android ecosystem received a significant boost as Google rolled out its March 2025 security update to Pixel devices, packed with crucial security patches and system stability improvements. Xiaomi users can expect the same in upcoming HyperOS updates, as the company tends to include these Android security patches in their regular update cycle. The comprehensive update fixes a series of critical vulnerabilities while continuing to boost the privacy features that Xiaomi has been working assiduously to improve across its large device lineup.
Major Security Upgrades Brought to Xiaomi Devices
The March 2025 security patch comprises numerous significant improvements that will benefit users of Xiaomi once it is implemented in HyperOS. These patches primarily focus on protecting user data and the system’s integrity.
File System Security Enhancements
Among the most important changes is restricted access to crucial Android directories:
- Android/data
- Android/obb
- Android/sandbox
This patch replaces the old path pattern matching with safer file equality tests to prevent potential directory traversal attacks from leaking user data.
Cross-Account Validation Fixes
The patch addresses vulnerabilities in StatusHint and TelecomServiceImpl component cross-account user icon validation. This corrects an issue with URIs of specific patterns not being parsed correctly, which might have caused unauthorized access between user accounts.
Bluetooth Security Improvements
Several significant fixes address memory vulnerabilities in the Bluetooth stack:
- Prevention of use-after-free in HID reports
- Utilization of encrypted links for AVDTP and AVCTP channels
- Solutions for memory-unsafe logging throughout the Bluetooth modules
Download Provider Protections
The recent security patch ensures ownership checking in the insert method of the download provider. Applications might have been able to read any file in Downloads by invoking this method without checking beforehand, but the patch now incorporates checking to ensure no record already exists in MediaProvider without the appropriate ownership checking.
What This Means for Xiaomi Users
Xiaomi’s commitment to security has been evidenced by its ongoing incorporation of Google’s security patches into HyperOS. These significant updates can be anticipated to be released in the coming weeks on eligible devices, bringing the high standard of security that Xiaomi is known for.
Its development team works hard to adapt these Android security patches to be suitable for HyperOS’s proprietary architecture so that protection, as well as performance, is guaranteed for their extensive line of devices.
When to Expect the Update
Although Xiaomi hasn’t announced the exact release date for these security updates yet, based on the previous update patterns, users can anticipate receiving the notifications within 2-3 weeks of Google’s initial release. Flagship models like the Xiaomi 16 series will receive the updates first, followed by the Redmi and POCO series.
Don’t forget to have your device settings configured to automatically check for updates so that you can receive these critical security updates as soon as they become available.

update and phone
me parece muy bien la iniciativa de Xiaomi de “invertir” en lo que es la seguridad del usuario pongo comillas porque más que una inversión lo que hacen más bien son pequeños cambios en el sistema sin embargo es una acción a destacar!
hoy me llegó una parche de seguridad para mi redmi 13 note en la aplicación meme OS pero al descargar y querer actualizar el paquete de actualización me sale un cartel que dice que no se puede verificar la actualización y no se puede instalar una ROM no oficial. realmente no entiendo porque. dos veces descargue el paquete y lo comprobé dos veces pero me dió el mismo error
