CVE-2026-8936: CWE-674 Uncontrolled Recursion in Docker Docker Desktop
CVE-2026-8936 is a high-severity vulnerability in Docker Desktop versions including 4. 33. 0, involving uncontrolled recursion in the grpcfuse kernel module. This flaw caused a virtual machine panic when a container created deeply nested directories on a bind-mounted host folder, triggering a dentry invalidation event. The issue has been fixed in Docker Desktop version 4. 76. 0.
AI Analysis
Technical Summary
This vulnerability (CWE-674) in Docker Desktop's grpcfuse kernel module results from unbounded recursion when handling deeply nested directories created by containers on bind-mounted host folders. This leads to a VM panic due to dentry invalidation events. The problem affects Docker Desktop version 4.33.0 and was addressed in version 4.76.0.
Potential Impact
Exploitation of this vulnerability can cause a virtual machine panic, resulting in denial of service conditions for affected Docker Desktop environments. The CVSS 4.0 score is 8.2 (high severity), indicating significant impact on availability with low attack complexity and no user interaction required. There are no known exploits in the wild at this time.
Mitigation Recommendations
A fix for this vulnerability is available in Docker Desktop version 4.76.0. Users should upgrade to this version or later to remediate the issue. Since this is not a cloud service, remediation depends on applying the official update. Patch status beyond this fix is not explicitly stated, so users should verify with Docker's official advisories for any additional guidance.
