Improper input validation in the SMM Supervisor may allow an attacker with a compromised SMI handler to gain Ring0 access potentially leading to arbitrary code execution. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

A race condition in System Management Mode (SMM) code may allow an attacker using a compromised user space to leverage CVE-2018-8897 potentially resulting in privilege escalation. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.

Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.

Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.

Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.

Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access. Rated medium severity (CVSS 4.4), this vulnerability is low attack complexity. No vendor patch available.

An attacker with specialized hardware and physical access to an impacted device may be able to perform a voltage fault injection attack resulting in compromise of the ASP secure boot potentially. Rated medium severity (CVSS 6.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.

A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. Rated medium severity (CVSS 4.7). Public exploit code available and no vendor patch available.

Insufficient input validation in CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting an arbitrary bit in an attacker-controlled pointer potentially leading to arbitrary. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.

Insufficient control flow management in AmdCpmGpioInitSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to escalation of privileges. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.

Insufficient control flow management in AmdCpmOemSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to an escalation of privileges. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.

When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure. Rated medium severity (CVSS 4.7). No vendor patch available.

IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.

A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.

Insufficient DRAM address validation in System Management Unit (SMU) may result in a DMA read from invalid DRAM address to SRAM resulting in SMU not servicing further requests. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.

Insufficient bounds checking in System Management Unit (SMU) may cause invalid memory accesses/updates that could result in SMU hang and subsequent failure to service any further requests from other. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. No vendor patch available.
