AMD PMF Vulnerability Allows Unmapped Memory Attack and Privilege Escalation

Improper input validation within the AMD Platform Management Framework (PMF) could allow an attacker to unmap arbitrary memory pages potentially impacting integrity and availability, or allowing privilege escalation resulting in loss of confidentiality.

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.

Out‑of‑Bounds Read in Power‑Management Firmware Enables Partial Confidentiality and Availability Loss

An out-of-bounds read in power management firmware by a malicious local attacker with low privileges could potentially lead to a partial loss of confidentiality and availability.

Improper cleanup in AMD CPU microcode patch loading could allow an attacker with local administrator privilege to load malicious CPU microcode, potentially resulting in loss of integrity of x86 instruction execution.

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 AMD Graphics Driver could allow a local attacker to write out of bounds, potentially resulting in loss of integrity or denial of service.

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