CVSS v3.1 |
| A compromised Trusted OS (TOS) driver could issue a malformed call that could potentially allow memory access outside the intended range resulting in loss of integrity. |
| A buffer overflow in the AMD Secure Processor (ASP) bootloader could allow an attacker to overwrite memory, potentially resulting in privilege escalation and arbitrary code execution. |
| Improper system call parameter validation in the Trusted OS may allow a malicious driver to perform mapping or unmapping operations on a large number of pages, potentially resulting in kernel memory corruption. |
| Improper input validation in system management mode (SMM) could allow a privileged attacker to overwrite stack memory leading to arbitrary code execution. |
| Improper input validation in the SMM handler could allow an attacker with Ring0 access to write to SMRAM and modify execution flow for S3 (sleep) wake up, potentially resulting in arbitrary code execution. |
| Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity. |
| Insufficient input parameter sanitization in AMD Secure Processor (ASP) Boot Loader (legacy recovery mode only) could allow an attacker to write out-of-bounds to corrupt Secure DRAM potentially resulting in denial of service. |
| Insufficient parameter sanitization in AMD Secure Processor (ASP) Boot Loader could allow an attacker with access to SPIROM upgrade to overwrite the memory, potentially resulting in arbitrary code execution. |
| A Time-of-check time-of-use (TOCTOU) race condition in the SMM communications buffer could allow a privileged attacker to bypass input validation and perform an out of bounds read or write, potentially resulting in loss of confidentiality, integrity, or availability. |
| Insufficient bounds checking in AMD TEE (Trusted Execution Environment) could allow an attacker with a compromised userspace to invoke a command with malformed arguments leading to out of bounds memory access, potentially resulting in loss of integrity or availability. |
| Insufficient parameter validation while allocating process space in the Trusted OS (TOS) may allow for a malicious userspace process to trigger an integer overflow, leading to a potential denial of service. |
| Improper syscall input validation in ASP (AMD Secure Processor) may force the kernel into reading syscall parameter values from its own memory space allowing an attacker to infer the contents of the kernel memory leading to potential information disclosure. |
| Failure to validate the address and size in TEE (Trusted Execution Environment) may allow a malicious x86 attacker to send malformed messages to the graphics mailbox resulting in an overlap of a TMR (Trusted Memory Region) that was previously allocated by the ASP bootloader leading to a potential loss of integrity. |
| Incomplete cleanup after loading a CPU microcode patch may allow a privileged attacker to degrade the entropy of the RDRAND instruction, potentially resulting in loss of integrity for SEV-SNP guests. |
| Improper isolation of shared resources on a system on a chip by a malicious local attacker with high privileges could potentially lead to a partial loss of integrity. |
| Improper handling of direct memory writes in the input-output memory management unit could allow a malicious guest virtual machine (VM) to flood a host with writes, potentially causing a fatal machine check error resulting in denial of service. |
| Improper cleanup in AMD CPU microcode patch loading could allow an attacker with local administrator privilege to load malicious CPU microcode, potentially resulting in loss of integrity of x86 instruction execution. |
| Use of an uninitialized variable in the ASP could allow an attacker to access leftover data from a trusted execution environment (TEE) driver, potentially leading to loss of confidentiality. |
| Insufficient verification of multiple header signatures while loading a Trusted Application (TA) may allow an attacker with privileges to gain code execution in that TA or the OS/kernel. |
| The AMD Ryzen processor with AGESA microcode through 2017-01-27 allows local users to cause a denial of service (system hang) via an application that makes a long series of FMA3 instructions, as demonstrated by the Flops test suite. |
