Amd: >> Epyc 73f3 Security Vulnerabilities
An attacker with a compromised ASP could
possibly send malformed commands to an ASP on another CPU, resulting in an out
of bounds write, potentially leading to a loss a loss of integrity.

Insufficient bounds checking in ASP may allow an
attacker to issue a system call from a compromised ABL which may cause
arbitrary memory values to be initialized to zero, potentially leading to a
loss of integrity.

A compromised or malicious ABL or UApp could
send a SHA256 system call to the bootloader, which may result in exposure of
ASP memory to userspace, potentially leading to information disclosure.
