CVE-2026-8936 · Severity: info · CVSS 8.2 · Published 2026-06-02

A vulnerability in Docker Desktop could allow a local user to crash the underlying virtual machine. By creating deeply nested folders within a shared directory, a container can trigger a system failure (kernel panic). This results in a denial of service, impacting the availability of the Docker environment and any running applications.

## Technical details

An uncontrolled recursion vulnerability (CWE-674) exists in the grpcfuse kernel module of Docker Desktop. The issue is triggered when a container creates deeply nested directories on a bind-mounted host folder, subsequently triggering a dentry invalidation event. This leads to a kernel panic within the Docker Desktop virtual machine. The attack requires local access with low privileges to create files within a bind mount. A fix is available in Docker Desktop version 4.76.0.

## Affected products

- Docker Docker Desktop before 4.76.0
