Insufficient verification of data authenticity may allow a local attacker to bypass Secure Debug Unlock (SDU), potentially resulting in unauthorized debug access.

Missing Lock Bit Protection in the Northbridge IO (NBIO) could allow a privileged attacker to use an intentionally disabled device as part of a remapping attack potentially impacting data confidentiality, integrity, or availability.

Improper isolation of shared resources within the CPU operation cache on Zen 2-based products could allow an attacker to corrupt instructions executed at a different privilege level, potentially resulting in privilege escalation.

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 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 input validation in system management mode (SMM) could allow a privileged attacker to overwrite stack memory leading to 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 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.
