Double Free Vulnerability in AMD Kernel Mode Driver

Release of an invalid pointer in the AMD kernel mode driver (KMD) could allow a privileged attacker to create a double free condition potentially leading to arbitrary code execution.

Trusted OS Driver Vulnerability Allowing Out‑of‑Bounds Memory Access

A compromised Trusted OS (TOS) driver could issue a malformed call that could potentially allow memory access outside the intended range resulting in loss of integrity.

Time‑Of‑Check to Time‑Of‑Use Race Condition in AMD Graphics Interface

A TOCTOU (Time-Of-Check to Time-Of-Use) in the graphics interface may allow an attacker to load registers repeatedly creating a race condition potentially leading to a loss of integrity.

Insufficient parameter validation while allocating process space in the Trusted OS (TOS) may allow for a malicious userspace process to trigger an integer overflow, leading to a potential denial of service.

Improper handling of insufficiency privileges in the ASP could allow a privileged attacker to modify Translation Map Registers (TMRs) potentially resulting in loss of confidentiality or integrity.

Improper input validation in the AMD Graphics Driver could allow an attacker to supply a specially crafted pointer, potentially leading to arbitrary writes or denial of service.

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.
