Insufficient checking of memory buffer in AMD Secure Processor (ASP) Secure OS may allow an attacker with a malicious trusted application to read/write to the ASP Secure OS kernel virtual address space, potentially resulting in privilege escalation.

GPU kernel implementations susceptible to memory leak

A GPU kernel can read sensitive data from another GPU kernel (even from another user or app) through an optimized GPU memory region called _local memory_ on various architectures.

hw: amd: SPI bypass

Improper Access Control in the AMD SPI protection feature may allow a user with Ring0 (kernel mode) privileged access to bypass protections potentially resulting in loss of integrity and availability.

hw: amd: AMD Radeon Graphics Kernel Driver Privilege Management Vulnerability

An improper privilege management in the AMD Radeon™ Graphics driver may allow an authenticated attacker to craft an IOCTL request to gain I/O control over arbitrary hardware ports or physical addresses resulting in a potential arbitrary code execution.

amd: Return Address Predictor vulnerability leading to information disclosure

A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.
