Search vulnerabilities
An observable timing discrepancy in the ASP could allow a privileged attacker to perform a brute-force attack against the hash message authentication code, allowing the input of an arbitrary message, potentially leading to a loss of data integrity.
hw: AMD: SMM Memory Corruption Vulnerability
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.
AMD RAID Driver Improper Input Validation Enables Privilege Escalation and Arbitrary Code Execution
Improper Input Validation in the AMD RAID driver could allow an attacker to point to an arbitrary memory location potentially resulting in privilege escalation and arbitrary code execution.
AMD Secure Processor Power‑Save State Tampering May Hijack Video Core Firmware
Improperly preserved integrity of hardware configuration state during a power save/restore operation in the AMD Secure Processor (ASP) could allow an attacker with the ability to write outside the trusted memory range (TMR) to change the execution flow of the Video Core Next (VCN) firmware potentially impacting confidentiality, integrity, or availability.
Local Privilege Attack via AGESA Bootloader PMIC Leads to Memory Denial of Service
Insecure default configuration state of DDR5 memory module by AGESA Bootloader Firmware could allow an attacker with local user privilege to abuse the unprotected PMIC interface to create a permanent denial of service condition or affect the integrity of the memory module.
Out-of-Bounds Access in AMD System Management Mode Communication Buffer
Improper input validation in the System Management Mode (SMM) communications buffer could allow a privileged attacker to perform an out of bounds read or write to a limited section of the Top of Memory Segment (TSEG) memory region, potentially resulting in loss of confidentiality or integrity.
Speculative Execution Bypass via Improper LFENCE Enforcement Leading to Potential Data Disclosure
Improper enforcement of the LFENCE serialization property may allow an attacker to bypass speculation barriers and potentially disclose sensitive information, potentially resulting in loss of confidentiality.
AMD Platform Configuration Blob: APCB SMM driver: kernel: linux-firmware: AMD APCB SMM driver: Arbitrary Code Execution via incorrect boot service use
Incorrect use of boot service in the AMD Platform Configuration Blob (APCB) SMM driver could allow a privileged attacker with local access (Ring 0) to achieve privilege escalation potentially resulting in arbitrary code execution.
Improper input validation in AMD Graphics Driver could allow an attacker to supply a specially crafted pointer, potentially 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.
A DLL hijacking vulnerability in the AMD Software Installer could allow an attacker to achieve privilege escalation potentially resulting in arbitrary code execution.
Improper Access Control in an on-chip debug interface could allow a privileged attacker to enable a debug interface and potentially compromise data confidentiality or integrity.
Integer Overflow within atihdwt6.sys can allow a local attacker to cause out of bound read/write potentially leading to loss of confidentiality, integrity and availability
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 restriction of operations within the bounds of a memory buffer in PCIe® Link could allow an attacker with access to a guest virtual machine to potentially perform a denial of service attack against the host resulting in loss of availability.
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.
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.
The integer overflow vulnerability within AMD Graphics driver could allow an attacker to bypass size checks potentially resulting in a denial of service
Insufficient protections in System Management Mode (SMM) code may allow an attacker to potentially enable escalation of privilege via local access.
