Android 6.0.1 March security patch:

The Android March security release fixes about 16 security bugs discovered and patched by the Android and Chrome security team along with other independent researchers. Some of these exploits are rated critical with remote code execution ability through email, MMS, and web browsing. It is an important security update as the bugs range from moderate to critical in their severity rating. While Google claims that there are no reports of these exploits being used in the wild, users are recommended to update their Nexus devices to the latest firmware update as soon as they receive the over the air notification.

The most severe of these issues is a Critical security vulnerability that could enable remote code execution on an affected device through multiple methods such as email, web browsing, and MMS when processing media files.
