Improper isolation of VCN-JPEG HW register space could allow a malicious Guest Virtual Machine (VM) or a process to perform unauthorized access to the register space of the JPEG cores assigned a victim VM/process, potentially gaining arbitrary read/write access to the victim VM/process data.

Security readout for executives and security teams

Plain-English summary

This AMD GPU issue weakens isolation around JPEG hardware registers. In the wrong local or virtualized setup, a malicious guest VM or local process could access data belonging to another VM or process. The business risk is highest where affected GPUs are shared across tenants, workloads, or trust boundaries.

Executive priority

Treat this as a high-priority infrastructure exposure where affected AMD GPUs support shared or isolated workloads. Standalone workstations are lower urgency than cloud, lab, AI, or virtualization hosts crossing trust boundaries.

Technical view

CVE-2024-36323 is an improper access control issue in VCN-JPEG hardware register isolation. The CVSS 4.0 score is 8.8 high. A local low-privileged attacker, with a required attack condition, may gain unauthorized register-space access and arbitrary read/write access to victim VM or process data.

Likely exposure

Exposure appears limited to systems using listed AMD Radeon RX 7000, Radeon PRO W7000, or Instinct MI300/MI325/MI308 products with the cited software or ROCm/ROC versions, especially GPU-sharing, passthrough, or multi-process environments.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. The attack is local and relevant when an attacker can run a malicious guest VM or process near protected GPU workloads.

Researcher notes

The source bundle does not include exploit details, proof of active exploitation, or precise fixed-version mapping beyond AMD’s advisory reference. Validate exposure by product, driver stack, and isolation model before assigning operational risk.

Mitigation direction

  • Review AMD-SB-6027 for official remediation and corrected software guidance.
  • Prioritize remediation on shared GPU, VM, passthrough, and multi-tenant systems.
  • Restrict untrusted VM or process access to affected GPU JPEG resources where feasible.
  • Avoid treating GPU sharing as a strong isolation boundary until remediated.
  • Monitor AMD and CVE records for updated fixed-version details.

Validation and detection

  • Inventory systems with affected Radeon RX 7000, Radeon PRO W7000, and Instinct products.
  • Compare installed Radeon Software, PRO Edition, ROCm, or ROC versions with AMD-SB-6027.
  • Identify workloads using GPU sharing, VM passthrough, or tenant-separated GPU access.
  • Check whether affected hosts process sensitive data from multiple trust zones.
  • Track KEV status separately; the provided bundle marks KEV as false.
