Radeon™ Software Crimson ReLive Edition

A potential vulnerability was reported in Radeon™ Software Crimson ReLive Edition which may allow escalation of privilege. Radeon™ Software Crimson ReLive Edition falls outside of the security support lifecycle and AMD does not plan to release any mitigations

Software based Power Side Channel on AMD CPUs

A potential power side-channel vulnerability in AMD processors may allow an authenticated attacker to monitor the CPU power consumption as the data in a cache line changes over time potentially resulting in a leak of sensitive information.

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.

amd: Return Address Predictor vulnerability leading to information disclosure

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.

Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.

Insufficient validation in the IOCTL (Input Output Control) input buffer in AMD Ryzen™ Master may permit a privileged attacker to perform memory reads/writes potentially leading to a loss of confidentiality or arbitrary kernel execution.

Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.

Insufficient validation in the IOCTL (Input Output Control) input buffer in AMD uProf may allow an authenticated user to load an unsigned driver potentially leading to arbitrary kernel execution.

Insufficient validation of the IOCTL (Input Output Control) input buffer in AMD μProf may allow an authenticated user to send an arbitrary address potentially resulting in a Windows crash leading to denial of service.

Insufficient validation of the IOCTL (Input Output Control) input buffer in AMD Ryzen™ Master may allow a privileged attacker to provide a null value potentially resulting in a Windows crash leading to denial of service.

Insufficient validation of the IOCTL (Input Output Control) input buffer in AMD μProf may allow an authenticated user to send an arbitrary buffer potentially resulting in a Windows crash leading to denial of service.

Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service.

Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical access to expose the contents of ASP memory potentially leading to a loss of confidentiality.

TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service.

A Use-After-Free vulnerability in the management of an SNP guest context page may allow a malicious hypervisor to masquerade as the guest's migration agent resulting in a potential loss of guest integrity.

hw: cpu: AMD: RetBleed Arbitrary Speculative Code Execution with Return Instructions

Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.

SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity.

hw: cpu: AMD: Branch Type Confusion (non-retbleed)

Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.

hw: cpu: cryptographic leaks via frequency scaling attacks(AMD)

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.

Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution.
