Verizon pushes new update to LG V20, see what's changed
The July patch addresses a number of Common Vulnerabilities and Exposures (CVEs), the most severe of which is related to a media framework vulnerability that could enable a remote attacker using a specially crafted file to execute arbitrary code within the context of a privileged process.
The update is available OTA, but it might need some time to reach all compatible devices. You can check for it manually by going to Settings > About Device > System Updates. As always, make sure that your phone is sufficiently charged and connected to a Wi-Fi network before proceeding with the patch.
