A potential vulnerability in the SMI callback function used in the EEPROM driver in some Lenovo Desktops and ThinkStation models may allow arbitrary code executionCVE-2017-3753lenovo group ltd.desktop and notebook bios+111EPSS score0.52%
A vulnerability has been identified in some Lenovo products that use UEFI (BIOS) code developed by American Megatrends, Inc. (AMI). With this vulnerability, conditions exist where an attacker with administrative privileges or physical access to a system may be able to run specially crafted code that can allow them to bypass system protections such as Device Guard and Hyper-V.CVE-2019-6170lenovo130-14ikb_firmware+392EPSS score0.35%
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.CVE-2019-6172lenovo130-14ikb_firmware+392EPSS score0.33%
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.CVE-2019-6156lenovo330-14igm_firmware+177EPSS score0.24%
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). Lenovo was notified that after resuming from S3 sleep mode in various versions of BIOS for Lenovo systems, the PRx is not set. This does not impact the SMM BIOS Write Protection, which keeps systems protected.CVE-2019-6188lenovo130-14ikb_firmware+391EPSS score1.32%
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.
