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.

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.

The integer overflow vulnerability within AMD Graphics driver could allow an attacker to bypass size checks potentially resulting in a denial of service

Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity.

Improper input validation in AMD Graphics Driver could allow an attacker to supply a specially crafted pointer, potentially leading to arbitrary code execution.

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

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.
