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 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.
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.
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.
