Uninitialized Resource in AMD Platform Management Framework Enables Kernel Memory Read

Use of uninitialized resource within the AMD Platform Management Framework (PMF) could allow an attacker to read a uninitialized kernel memory resulting in loss of confidentiality 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.

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 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.

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.

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.
