CVE-2021-46773 [HIGH] CWE-20 CVE-2021-46773: Insufficient input validation in ABL may enable a privileged attacker to corrupt ASP memory, potenti Insufficient input validation in ABL may enable a privileged attacker to corrupt ASP memory, potentially resulting in a loss of integrity or code execution.

CVE-2021-46756 [CRITICAL] CWE-20 CVE-2021-46756: Insufficient validation of inputs in SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader Insufficient validation of inputs in SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader may allow an attacker with a malicious Uapp or ABL to send malformed or invalid syscall to the bootloader resulting in a potential denial of service and loss of integrity.

CVE-2021-46760 [CRITICAL] CWE-119 CVE-2021-46760: A malicious or compromised UApp or ABL can send a malformed system call to the bootloader, which may A malicious or compromised UApp or ABL can send a malformed system call to the bootloader, which may result in an out-of-bounds memory access that may potentially lead to an attacker leaking sensitive information or achieving code execution.

CVE-2021-26356 [HIGH] CWE-367 CVE-2021-26356: A TOCTOU in ASP bootloader may allow an attacker to tamper with the SPI ROM following data read to m A TOCTOU in ASP bootloader may allow an attacker to tamper with the SPI ROM following data read to memory potentially resulting in S3 data corruption and information disclosure.

CVE-2021-46749 [HIGH] CWE-125 CVE-2021-46749: Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SM Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SMI (System Management Interface) mailbox checksum calculation triggering a data abort, resulting in a potential denial of service.

CVE-2021-46794 [HIGH] CWE-125 CVE-2021-46794: Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SM Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SMI (System Management Interface) mailbox checksum calculation triggering a data abort, resulting in a potential denial of service.

CVE-2021-46755 [HIGH] CVE-2021-46755: Failure to unmap certain SysHub mappings in error paths of the ASP (AMD Secure Processor) bootloader Failure to unmap certain SysHub mappings in error paths of the ASP (AMD Secure Processor) bootloader may allow an attacker with a malicious bootloader to exhaust the SysHub resources resulting in a potential denial of service.

CVE-2021-26406 [HIGH] CVE-2021-26406: Insufficient validation in parsing Owner's Certificate Authority (OCA) certificates in SEV (AMD Secu Insufficient validation in parsing Owner's Certificate Authority (OCA) certificates in SEV (AMD Secure Encrypted Virtualization) and SEV-ES user application can lead to a host crash potentially resulting in denial of service.

CVE-2021-26354 [MEDIUM] CWE-120 CVE-2021-26354: Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised 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.

CVE-2021-26371 [MEDIUM] CVE-2021-26371: A compromised or malicious ABL or UApp could send a SHA256 system call to the bootloader, which may 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.
