CVE ID | Published | Description | Score | Severity |
---|---|---|---|---|
Improper Access Control in the AMD SPI protection feature may allow a user with Ring0 (kernel mode) privileged access to bypass protections potentially resulting in loss of integrity and availability. | 6 |
Medium |
||
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. | 9.8 |
Critical |
||
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. | 8.1 |
High |
||
Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access. | 7.8 |
High |
||
Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access. | 7.8 |
High |
||
Insufficient validation of SPI flash addresses in the ASP (AMD Secure Processor) bootloader may allow an attacker to read data in memory mapped beyond SPI flash resulting in a potential loss of availability and integrity. | 6.1 |
Medium |
||
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 code execution in SMM. | 7.8 |
High |
||
A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure. | 4.7 |
Medium |
||
A bug in AMD CPU’s core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service. AMD believes the specific code includes a specific x86 instruction sequence that would not be generated by compilers. | 5.5 |
