Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access.

Dell BIOS contains an improper authentication vulnerability. A malicious user with physical access to the system may potentially exploit this vulnerability in order to modify a security-critical UEFI variable without knowledge of the BIOS administrator.

Dell BIOS contain a Time-of-check Time-of-use vulnerability in BIOS. A local authenticated malicious user with physical access to the system could potentially exploit this vulnerability by using a specifically timed DMA transaction during an SMI in order to gain arbitrary code execution on the system.

An attacker with specialized hardware and physical access to an impacted device may be able to perform a voltage fault injection attack resulting in compromise of the ASP secure boot potentially leading to arbitrary code execution. 

Insufficient input validation in CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting an arbitrary bit in an attacker-controlled pointer potentially leading to arbitrary code execution in SMM.

An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information.

Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user with administrator privileges may potentially exploit this vulnerability in order to modify a UEFI variable.
