Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.

Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.

A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure.

Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features potentially resulting in denial of resources and/or denial of service.

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.

An attacker with root account privileges can load any legitimately signed firmware image into the Audio Co-Processor (ACP,) irrespective of the respective signing key being declared as usable for authenticating an ACP firmware image, potentially resulting in a denial of service.

Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.

A malformed SMI (System Management Interface) command may allow an attacker to establish a corrupted SMI Trigger Info data structure, potentially leading to out-of-bounds memory reads and writes when triggering an SMI resulting in a potential loss of resources.

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.

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.
