Local Buffer Overflow in AMD Sensor Fusion Hub Driver May Cause Denial of Service
A buffer overflow vulnerability within AMD Sensor Fusion Hub Driver can allow a local attacker to write out of bounds, potentially resulting in denial of service or crash
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.
Debug code left active in AMD's Video Decoder Engine Firmware (VCN FW) could allow a attacker to submit a maliciously crafted command causing the VCN FW to perform read/writes HW registers, potentially impacting confidentiality, integrity and availabilability of the system.
Improper input validation in AMD Graphics Driver could allow an attacker to supply a specially crafted pointer, potentially leading to 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 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.
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 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.
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.
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.
The integer overflow vulnerability within AMD Graphics driver could allow an attacker to bypass size checks potentially resulting in a denial of service
A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow an attacker with ring0 privileges and access to the BIOS menu or UEFI shell to modify the communications buffer potentially resulting in arbitrary code execution.
