CVE-2022-27672

When SMT is enabled, certain AMD processors may speculatively execute instructions using a targetfrom the sibling thread after an SMT mode switch potentially resulting in information disclosure.

CVE-2021-26354

Insufficient bounds checking in ASP may allow anattacker to issue a system call from a compromised ABL which may causearbitrary memory values to be initialized to zero, potentially leading to aloss of integrity.

CVE-2021-26371

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