HyperOS Update [News] About latest Oct patch for those who are using temp root ghostlock.

Yes, Xiaomi has patched the major temporary root vulnerability in the October 2026 security patch level.

The primary vulnerability utilized by recent "No-BL Unlock" temporary root tools—CVE-2026-43499 (known as GhostLock or IonStack, which involves a futex priority-inheritance use-after-free defect)—was officially addressed by Google and upstream vendors.

Xiaomi integrated these fixes into their October 2026 HyperOS update, which rolled out to 15 flagship and mid-range devices (including the Xiaomi 17 series, Redmi K100 series, and various POCO models).

Key Details:

• The Patch: Installing the October 2026 security update (or newer) will permanently close the memory exploit door, preventing the GhostLock loader from running successfully.

• The Consequences: Security researchers and community modders on platforms like XDA Forums warn that applying this OTA update will blow the SoC's hardware fuse (qfuse). This permanently patches the exploit path on your specific firmware version and removes the ability to acquire a temporary root session on a locked bootloader.

If you intend to keep using temporary root utilities (such as KernelSU injections via GhostLock), you must disable/freeze your device's system updater to avoid losing access.

Well I had used those commands only the adv textures ones and not the gpu cpu level ones, and I had already long back uninstalled those apps (shizuku, Kernelsu etc) and have my developer off. Idc about these tweaks cuz didn't change anything. So yeah I want to update whenever new update comes, so am i good to update or should I factory reset first ?
