Out-of-Bounds Write in Lenovo ELAN TrackPoint Driver Enables Local Denial of Service

ELAN reported a potential out-of-bounds write vulnerability in the ELAN TrackPoint driver that, under certain circumstances, could allow a local authenticated user to cause a system crash.

During an internal security assessment, a potential vulnerability was discovered in some ThinkPad embedded controller firmware that could allow a privileged local user to perform arbitrary reads or writes to privileged memory regions.

Out‑of‑Bounds Write in Lenovo ThinkPad BIOS Enables System Management Mode Execution

During an internal security assessment, a potential out-of-bounds write vulnerability was discovered in the BIOS of some ThinkPad products could allow a privileged local user to execute code in System Management Mode (SMM).

Unspecified vulnerability in Lenovo Intel PRO/1000 LAN adapter before Build 135400, as used on IBM Lenovo ThinkPad systems, has unknown impact and attack vectors.

Lenovo BIOS Vulnerability Allowing Secure Boot Disablement

A potential vulnerability was reported in the BIOS of L13 Gen 6, L13 Gen 6 2-in-1, L14 Gen 6, and L16 Gen 2 ThinkPads which could result in Secure Boot being disabled even when configured as “On” in the BIOS setup menu. This issue only affects systems where Secure Boot is set to User Mode.

A potential vulnerability was reported in the ThinkPad L390 Yoga and 10w Notebook that could allow a local attacker to escalate privileges by accessing an embedded UEFI shell.

Improper BIOS Initialization Allowing Local Privilege Escalation on Lenovo ThinkPads

A potential improper initialization vulnerability was reported in the BIOS of some ThinkPads that could allow a local privileged user to modify data and 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.

An unquoted service path vulnerability was identified in the driver for the ThinkPad Compact USB Keyboard with TrackPoint versions earlier than 1.5.5.0. This could allow an attacker with local privileges to execute code with administrative privileges.

ThinkPad USB 3.0 Ethernet Adapter (part number 4X90E51405) driver, various versions, was found to contain a privilege escalation vulnerability that could allow a local user to execute arbitrary code with administrative or system level privileges.

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.

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 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.

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.

Untrusted search path vulnerability in Lenovo Thinkpad Bluetooth with Enhanced Data Rate Software 6.4.0.2900 and earlier allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse DLL that is located in the same folder as a file that is processed by Lenovo Bluetooth.

A buffer over-read vulnerability was reported in the ThinkPadX13s BIOS LenovoSetupConfigDxe driver that could allow a local attacker with elevated privileges to cause information disclosure.

A buffer over-read vulnerability was reported in the ThinkPadX13s BIOS driver that could allow a local attacker with elevated privileges to cause information disclosure.

A buffer over-read vulnerability was reported in the ThinkPadX13s BIOS LenovoRemoteConfigUpdateDxe driver that could allow a local attacker with elevated privileges to cause information disclosure.
