CVSS v3.1 |
| 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. |
| In the Lenovo Power Management driver before 1.67.12.24, a local user may alter the trackpoint's firmware and stop the trackpoint from functioning correctly. This issue only affects ThinkPad X1 Carbon 5th generation. |
| 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. |
| 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 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. |
| An information leak vulnerability in the SMI Set BIOS Password SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to read SMM memory. |
| A potential vulnerability in the LenovoFlashDeviceInterface SMI handler may allow an attacker with local access and elevated privileges to execute arbitrary code. |
|
A vulnerability due to improper write protection of UEFI variables was reported in the BIOS of some ThinkPad models could allow an attacker with physical or local access and elevated privileges the ability to bypass Secure Boot.
|
|
An SMI handler input validation vulnerability in the BIOS of some ThinkPad models could allow an attacker with local access and elevated privileges to execute arbitrary code.
|
| An SMM driver input validation vulnerability in the BIOS of some ThinkPad models could 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. |
| 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. |
| 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. |
| In Lenovo systems, SMM BIOS Write Protection is used to prevent writes to SPI Flash. While this provides sufficient protection, an additional layer of protection is provided by SPI Protected Range Registers (PRx). After resuming from S3 sleep mode in various versions of BIOS for some Lenovo ThinkPad systems, the PRx is not set. This does not impact the SMM BIOS Write Protection, which keeps systems protected. |
| Lenovo implemented Intel CSME Anti-rollback ARB protections on some ThinkPad models to prevent roll back of CSME Firmware in flash. |
| The BIOS tamper detection mechanism was not triggered in Lenovo ThinkPad A285, BIOS versions up to r0xuj70w; A485, BIOS versions up to r0wuj65w; T495 BIOS versions up to r12uj55w; T495s/X395, BIOS versions up to r13uj47w, while the emergency-reset button is pressed which may allow for unauthorized access. |
| 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. |
