CVE-2026-112917

CriticalCVSS 9.2
Published: Translated: NVD NIST

Summary

In Docker Desktop for Windows with the WSL2 backend, an unprivileged Linux container can use 32-bit socketcall to bypass the default seccomp restriction on AF_VSOCK. This can expose host-facing services and Windows files accessible to the logged-in user. The issue affects x86-64 WSL2; LinuxKit-based backends are unaffected.

Risk Assessment

A container may gain access to host services and files, breaking container isolation and potentially leading to privilege escalation or data leakage. Organizations running untrusted containers in Docker Desktop are especially exposed.

Recommendation

Update Docker Desktop to 4.98.0 or later and WSL to 3.0.3 or later — updating Docker Desktop alone while running an older WSL does not remediate the issue.

In Docker Desktop for Windows with the WSL2 backend, an unprivileged Linux container can use 32-bit socketcall to bypass the default seccomp restriction on AF_VSOCK. This can expose host-facing services and Windows files accessible to the logged-in user. The issue affects x86-64 WSL2; LinuxKit-based backends are unaffected. The issue is fully fixed only with Docker Desktop 4.98.0 or later and WSL 3.0.3 or later. Docker Desktop 4.98.0 or later running on an older WSL remains affected.
