Improper input and range checking in the AMD Secure Processor (ASP) boot loader image header may allow an attacker to use attacker-controlled values prior to signature validation potentially resulting in arbitrary code execution.

AMD System Management Unit (SMU) contains a potential issue where a malicious user may be able to manipulate mailbox entries leading to arbitrary code execution.

AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources.

A potential denial of service (DoS) vulnerability exists in the integrated chipset that may allow a malicious attacker to hang the system when it is rebooted.

AMD EPYC™ Processors contain an information disclosure vulnerability in the Secure Encrypted Virtualization with Encrypted State (SEV-ES) and Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP). A local authenticated attacker could potentially exploit this vulnerability leading to leaking guest data by the malicious hypervisor.

A side effect of an integrated chipset option may be able to be used by an attacker to bypass SPI ROM protections, allowing unauthorized SPI ROM modification.

Race condition in ASP firmware could allow less privileged x86 code to perform ASP SMM (System Management Mode) operations.
