A vulnerability has been identified in some Lenovo products that use UEFI (BIOS) code developed by American Megatrends, Inc. (AMI). With this vulnerability, conditions exist where an attacker with administrative privileges or physical access to a system may be able to run specially crafted code that can allow them to bypass system protections such as Device Guard and Hyper-V.

A denial of service vulnerability was reported in Lenovo System Update before version 5.07.0084 that could allow service log files to be written to non-standard locations.
