The Infineon RSA library 1.02.013 in Infineon Trusted Platform Module (TPM) firmware, such as versions before 0000000000000422 - 4.34, before 000000000000062b - 6.43, and before 0000000000008521 - 133.33, mishandles RSA key generation, which makes it easier for attackers to defeat various cryptographic protection mechanisms via targeted attacks, aka ROCA. Examples of affected technologies include BitLocker with TPM 1.2, YubiKey 4 (before 4.3.5) PGP key generation, and the Cached User Data encryption feature in Chrome OS.

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 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 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.

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 function to access EEPROM in some ThinkPad 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 CSME configuration of some Lenovo Notebook and ThinkPad systems could be used to leak out data out of the SMRAM range.

A denial of service vulnerability was reported in some ThinkPad models that could cause a system to crash when the Enhanced Biometrics setting is enabled in BIOS.

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.

A null pointer dereference vulnerability in Lenovo Power Management Driver for Windows 10, prior to version 1.67.17.54, that could cause systems to experience a blue screen error.

A privilege escalation vulnerability in Lenovo Power Management Driver for Windows 10, prior to version 1.67.17.54, that could allow unauthorized access to the driver's device object.

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

An unquoted search path vulnerability was reported in versions prior to 1.0.83.0 of the Synaptics Smart Audio UWP app associated with the DCHU audio drivers on Lenovo platforms that could allow an administrative user to execute arbitrary code.

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.

An internal shell was included in BIOS image in some ThinkPad models that could allow escalation of privilege.

ThinkPad T460p and T470p BIOS Tamper Mechanism

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.

There is a vulnerability with the Dolby DAX2 API system services in which a low-privileged user can terminate arbitrary processes that are running at a higher privilege.
