A GPU kernel can read sensitive data from another GPU kernel (even from another user or app) through an optimized GPU memory region called _local memory_ on various architectures.

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

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

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. 

A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. 

A potential power side-channel vulnerability in AMD processors may allow an authenticated attacker to monitor the CPU power consumption as the data in a cache line changes over time potentially resulting in a leak of sensitive information.

Certain size values in firmware binary headers could trigger out of bounds reads during signature validation, leading to denial of service or potentially limited leakage of information about out-of-bounds memory contents.
