A buffer overflow in the WMI SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to execute arbitrary code.

A potential vulnerability in the SMI callback function used in the SMBIOS event log driver in some Lenovo Desktop, ThinkStation, and ThinkEdge models may allow an attacker with local access and elevated privileges to execute arbitrary code.

A potential vulnerability in the SMI callback function used in the NVME driver in some Lenovo Desktop, ThinkStation, and ThinkEdge models may allow an attacker with local access and elevated privileges to execute arbitrary code.

A potential vulnerability in the SMI callback function that saves and restore boot script tables used for resuming from sleep state in some ThinkCentre and ThinkStation models may allow an attacker with local access and elevated privileges to execute arbitrary code.

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.
