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.
Insufficient General Purpose IO (GPIO) bounds check in System Management Unit (SMU) may result in access/updates from/to invalid address space that could result in denial of service.
Insufficient bound checks in the System Management Unit (SMU) may result in a system voltage malfunction that could result in denial of resources and/or possibly denial of service.
Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features potentially resulting in denial of resources and/or denial of service.
Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service.
Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access.
