Docker Desktop vulnerabilities

Docker Desktop 4.76.0 fixes a VM panic caused by unbounded recursion in the grpcfuse kernel module when deeply nested directories are created on a bind-mounted host folder and a dentry invalidation event is triggered.

The Docker CLI --use-api-socket flag bypasses Enhanced Container Isolation (ECI) restrictions in Docker Desktop. When ECI is enabled, Docker socket mounts from containers are denied unless explicitly allowed. The --use-api-socket flag adds the mount via HostConfig.Mounts instead of HostConfig.Binds, and ECI enforcement only inspects Binds, allowing the mount to pass unchecked. This grants a container full access to the Docker Engine socket and, if the host user is logged into container registries, their authentication credentials.

Docker Desktop Installer.exe is vulnerable to DLL hijacking due to insecure DLL search order. The installer searches for required DLLs in the user's Downloads folder before checking system directories, allowing local privilege escalation through malicious DLL placement. This issue affects Docker Desktop through 4.48.0.
