OS security patch channel for Linux, part of NodeOSUpgrade feature, is now generally available.
OS security patches are AKS-tested, fully managed, and applied with safe deployment practices. AKS regularly updates the node's virtual hard disk (VHD) with patches from the image maintainer labeled "security only."
This channel part of nodeosupgrade feature honors maintenance windows and limits disruption by applying live patching wherever necessary.
