Microsoft delivered a number of cumulative updates this Tuesday, including updates sent to Windows 7, Windows 8.1, and various versions of Windows 10. The company also started the process of re-releasing Windows 10 October 2018 Update, which was put on hold after a few data loss issues were reported by users.

It appears that the Windows maker has also started rolling out an update to Windows 10 Mobile. Nope, there are no obviously new features but it does bring security fixes.

Windows 10 Mobile (Build 15254.541 – KB4469220) brings fixes to several vulnerabilities. The company wrote that the build “includes all the improvements from KB4467696.” The changelog for KB4467696 (Windows 10 version 1703 build 15063.1446) carries the following fixes:

  • Provides protections against an additional subclass of speculative execution side-channel vulnerability known as Speculative Store Bypass (CVE-2018-3639) for AMD-based computers. These protections aren’t enabled by default. For Windows client (IT pro) guidance, follow the instructions in KB4073119. For Windows Server guidance, follow the instructions in KB4072698. Use these guidance documents to enable mitigations for Speculative Store Bypass (CVE-2018-3639). Additionally, use the mitigations that have already been released for Spectre Variant 2 (CVE-2017-5715) and Meltdown (CVE-2017-5754).
  • Security updates to Windows Scripting, Internet Explorer, Microsoft Edge, Windows App Platform and Frameworks, Windows Graphics, Windows Kernel, and Windows Server.
