HP has identified a potential vulnerability in BIOS firmware of some Workstation products. Firmware updates are being released to mitigate these potential vulnerabilities.

A buffer overflow in the SystemBootManagerDxe driver in some Lenovo Notebook products may allow an attacker with local privileges to execute arbitrary code.

A potential vulnerability in the WMI Setup driver on some consumer Lenovo Notebook devices may allow an attacker with elevated privileges to modify secure boot setting by modifying an NVRAM variable.

A potential vulnerability in AMD System Management Mode (SMM) interrupt handler may allow an attacker with high privileges to access the SMM resulting in arbitrary code execution which could be used by malicious actors to bypass security mechanisms provided in the UEFI firmware.

A potential vulnerability in the SMI callback function used in the Legacy BIOS mode driver in some Lenovo Notebook models may allow an attacker with local access and elevated privileges to execute arbitrary code.
