Security readout for executives and security teams
Plain-English summary
CVE-2021-26360 is a high-severity AMD graphics driver issue. A local attacker could alter security-related SoC register configuration, potentially corrupting encrypted memory used by the AMD Secure Processor and leading to code execution inside that processor.
Executive priority
Prioritize remediation on shared workstations, developer systems, and high-value endpoints. The issue is high impact but locally triggered, so urgency depends on how easily attackers or untrusted users can gain local access.
Technical view
The flaw is CWE-284 improper access control affecting AMD Radeon RX 6000 Series and PRO W6000 Series software stacks. CVSS 3.1 is 7.8 with local attack vector, low complexity, low privileges, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely on workstations or endpoints using AMD Radeon RX 6000 Series or PRO W6000 Series GPUs with AMD Radeon Software, Radeon Pro Software Enterprise, or Enterprise Driver versions covered by AMD-SB-1029.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. The vulnerability requires local access and low privileges, so it is primarily a local escalation or post-compromise hardening concern rather than a remote internet-exposed issue.
Researcher notes
The public description links unauthorized SoC register security configuration changes to possible AMD Secure Processor encrypted-memory corruption and arbitrary ASP code execution. The source bundle does not include exploit details, proof of exploitation, or specific fixed version data.
Mitigation direction
- Review AMD-SB-1029 for vendor-designated fixed driver versions.
- Update affected AMD Radeon and Radeon Pro driver packages.
- Prioritize systems where untrusted users can obtain local access.
- Restrict unnecessary local account access until remediation is complete.
- Track AMD security bulletins for any revised guidance.
Validation and detection
- Inventory endpoints with AMD Radeon RX 6000 or PRO W6000 GPUs.
- Identify installed AMD Radeon, Radeon Pro, or Enterprise Driver versions.
- Compare installed versions against AMD-SB-1029 guidance.
- Confirm updated driver packages are deployed successfully.
- Document exceptions where affected hardware remains unpatched.

Improper Access Control
Improper Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
