Lenovo Thinkpad X250

A local privilege escalation vulnerability was identified in the Realtek audio driver versions prior to 6.0.1.8224 in some Lenovo ThinkPad products. An attacker with local privileges could execute code with administrative privileges.

In some Lenovo ThinkPads, an unquoted search path vulnerability was found in various versions of the Synaptics Pointing Device driver which could allow unauthorized code execution as a low privilege user.

Realtek Audio Drivers for Windows, as used on the Lenovo ThinkPad X1 Carbon 20A7, 20A8, 20BS, and 20BT before 6.0.8882.1 and 20KH and 20KG before 6.0.8907.1 (and on many other Lenovo and non-Lenovo products), mishandles DLL preloading.

A potential vulnerability in the SMI callback function used to access flash device in some ThinkPad models may allow an attacker with local access and elevated privileges to execute arbitrary code.

During an internal product security audit a potential vulnerability due to use of Boot Services in the SmmOEMInt15 SMI handler was discovered in some ThinkPad models could be exploited by an attacker with elevated privileges that could allow for execution of code.

Some Lenovo Notebook, ThinkPad, and Lenovo Desktop systems have BIOS modules unprotected by Intel Boot Guard that could allow an attacker with physical access the ability to write to the SPI flash storage.

A potential vulnerability in the SMI callback function used in the Legacy SD driver in some Lenovo ThinkPad, ThinkStation, and Lenovo Notebook models may allow arbitrary code execution.

A potential vulnerability in the SMI callback function used in CSME configuration of some Lenovo Notebook and ThinkPad systems could be used to leak out data out of the SMRAM range.
