The November Android updates for applicable Pixel and Nexus devices does not contain the November 6 level security patch.
The big deal here is that the KRACK vulnerability that has left pretty much all Wi-Fi traffic painfully open to interception and manipulation is patched at this level and not on the November 5 level update that these devices received.
Apparently, some people have been taken aback by this shortfall, so language on the Pixel/Nexus security bulletin has been clarified — the phones and tablet-likes are receiving the November 5 patch.
Lest we forget that the KRACK vulnerability has already been patched on the Essential Phone, which has Android 7.1.1.
