| A buffer over-read was reported in the LemSecureBootForceKey module in some Lenovo Desktop products that may allow a local attacker with elevated privileges to disclose sensitive information. |
| A buffer overflow was reported in the LemSecureBootForceKey module in some Lenovo Desktop products that may allow a local attacker with elevated privileges to execute arbitrary code. |
| A potential vulnerability in the SMI callback function used in the SMBIOS event log driver in some Lenovo Desktop, ThinkStation, and ThinkEdge 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 the NVME driver in some Lenovo Desktop, ThinkStation, and ThinkEdge models may allow an attacker with local access and elevated privileges to execute arbitrary code. |
| A read-only authentication bypass vulnerability was reported in the Third Quarter 2021 release of Lenovo XClarity Controller (XCC) firmware affecting XCC devices configured in LDAP Authentication Only Mode and using an LDAP server that supports “unauthenticated bind”, such as Microsoft Active Directory. An unauthenticated user can gain read-only access to XCC in such a configuration, thereby allowing the XCC device configuration to be viewed but not changed. XCC devices configured to use local authentication, LDAP Authentication + Authorization Mode, or LDAP servers that support only “authenticated bind” and/or “anonymous bind” are not affected. |
| A potential vulnerability in the SMI callback function that saves and restore boot script tables used for resuming from sleep state in some ThinkCentre and ThinkStation models may allow an attacker with local access and elevated privileges to execute arbitrary code. |
| A vulnerability was reported in some Lenovo Desktop models that could allow unauthorized access to the boot menu, when the "BIOS Password At Boot Device List" BIOS setting is Yes. |
| Prior to August 10, 2020, some Lenovo Desktop and Workstation systems were shipped with the Embedded Host Based Configuration (EHBC) feature of Intel AMT enabled. This could allow an administrative user with local access to configure Intel AMT. |
| A potential vulnerability in the SMI callback function used in the EEPROM driver in some Lenovo Desktops and ThinkStation models may allow arbitrary code execution |
| A potential vulnerability in the SMI callback function used in the System Lock Preinstallation driver in some Lenovo Notebook and ThinkStation models may allow arbitrary code execution. |
| Lenovo was notified of a potential denial of service vulnerability, affecting various versions of BIOS for Lenovo Desktop, Desktop - All in One, and ThinkStation, that could cause PCRs to be cleared intermittently after resuming from sleep (S3) on systems with Intel TXT enabled. |
| 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. |
| A vulnerability reported in Lenovo Service Bridge before version 4.1.0.1 could allow unencrypted downloads over FTP. |
| A vulnerability reported in Lenovo Service Bridge before version 4.1.0.1 could allow remote code execution. |
| A vulnerability reported in Lenovo Service Bridge before version 4.1.0.1 could allow remote code execution. |
| A vulnerability reported in Lenovo Service Bridge before version 4.1.0.1 could allow cross-site request forgery. |
| A denial of service vulnerability was reported in Lenovo System Update before version 5.07.0084 that could allow service log files to be written to non-standard locations. |
| 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. |
