Google releases May security patch for Nexus and Pixel devices7
The following devices will receive Android 7.1.2 update with the May security patch: Pixel XL, Pixel, Nexus 6P, Nexus 5X, Nexus Player and Pixel C. The Nexus 6 and Nexus 9 get the security update with Android 7.1.1.
According to Google, all supported Google devices will receive a single OTA update with the May 5, 2017, security patch. However, since the search giant has already published the OTA files and factory images, Pixel and Nexus owners can manually installed the security update.
Along with these images, Google released the Android security bulletin for May, which contains all the information about the changes included in the update. Still, it's worth mentioning that the most severe of these issues is a critical security vulnerability that could enable remote code execution on an affected device via email, web browsing, and MMS when processing media files.
If you don't want to manually flash the update on your Google device, the May security patch should arrive OTA in the next couple of days.
