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…
Insufficient input validation in ABL may enable a privileged attacker to corrupt ASP memory, potentially resulting in a loss of integrity or code execution.
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 achi…
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…
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 se…
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…
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 ser…
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.
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.
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.
