CVE Feed

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.

Improper syscall input validation in AMD TEE (Trusted Execution Environment) may allow an attacker with physical access and control of a Uapp that runs under the bootloader to reveal the contents of the ASP (AMD Secure Processor) bootloader accessible memory to a serial port, resulting in a potential loss of integrity.

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.

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.

Insufficient input validation in the ASP (AMD Secure Processor) bootloader may allow an attacker with a compromised Uapp or ABL to coerce the bootloader into exposing sensitive information to the SMU (System Management Unit) resulting in a potential loss of confidentiality and integrity.

Failure to validate the length fields of the ASP (AMD Secure Processor) sensor fusion hub headers may allow an attacker with a malicious Uapp or ABL to map the ASP sensor fusion hub region and overwrite data structures leading to a potential loss of confidentiality and integrity.

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.

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.

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.

Certain size values in firmware binary headers could trigger out of bounds reads during signature validation, leading to denial of service or potentially limited leakage of information about out-of-bounds memory contents.

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.

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.

Improper access control settings in ASP Bootloader may allow an attacker to corrupt the return address causing a stack-based buffer overrun potentially leading to arbitrary code execution.

Insufficient input validation on the model specific register: VM_HSAVE_PA may potentially lead to loss of SEV-SNP guest memory integrity.

Improper input validation in ABL may enable an attacker with physical access, to perform arbitrary memory overwrites, potentially leading to a loss of integrity and code execution.

Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to execute arbitrary DMA copies, which can lead to code execution.

Improper validation of DRAM addresses in SMU may allow an attacker to overwrite sensitive memory locations within the ASP potentially resulting in a denial of service.

Insufficient input validation in the SMU may enable a privileged attacker to write beyond the intended bounds of a shared memory buffer potentially leading to a loss of integrity.

Insufficient input validation in the SMU may allow an attacker to corrupt SMU SRAM potentially leading to a loss of integrity or denial of service.

Insufficient address validation, may allow an attacker with a compromised ABL and UApp to corrupt sensitive memory locations potentially resulting in a loss of integrity or availability.

Insufficient input validation of mailbox data in the SMU may allow an attacker to coerce the SMU to corrupt SMRAM, potentially leading to a loss of integrity and privilege escalation.
