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.
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.
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.
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.
The BIOS tamper detection mechanism was not triggered in Lenovo ThinkPad T460p, BIOS versions up to R07ET90W, and T470p, BIOS versions up to R0FET50W, which may allow for unauthorized access.
A potential vulnerability in the SMI callback function used in Legacy USB driver using passed parameter without sufficient checking in some Lenovo ThinkPad models may allow arbitrary code execution.
A potential vulnerability in the SMI callback function used in the Legacy USB driver using boot services structure in runtime phase in some Lenovo ThinkPad models may allow arbitrary code execution.
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.
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.
A privilege escalation vulnerability was identified in Lenovo Active Protection System for ThinkPad systems versions earlier than 1.82.0.17. An attacker with local privileges could execute code with administrative privileges via an unquoted service path.
A vulnerability has been identified in a signed kernel driver for the BIOS of some ThinkPad systems that can allow an attacker with Windows administrator-level privileges to call System Management Mode (SMM) services. This could lead to a denial of service attack or allow certain BIOS variables or settings to be altered (such as boot sequence). The setting or changing of BIOS passwords is not affected by this vulnerability.
