CVE-2017-16539: The DefaultLinuxSpec function in oci/defaults.go in Docker Moby through 17.03.2-ce does not block /proc/scs...

The DefaultLinuxSpec function in oci/defaults.go in Docker Moby through 17.03.2-ce does not block /proc/scsi pathnames, which allows attackers to trigger data loss (when certain older Linux kernels are used) by leveraging Docker container access to write a "scsi remove-single-device" line to /proc/scsi/scsi, aka SCSI MICDROP.

Security readout for executives and security teams

Plain-English summary

This issue lets someone with Docker container access cause host-side data loss on certain older Linux kernels because Docker Moby did not block a sensitive /proc/scsi path. It is not described as data theft or remote takeover, but availability impact can be serious where vulnerable Docker and kernel conditions exist.

Executive priority

Treat this as a legacy-container availability risk. It does not justify emergency response absent affected hosts, but organizations with old Docker infrastructure should validate quickly because the potential impact is host data loss or service disruption.

Technical view

Docker Moby through 17.03.2-ce generated a default Linux OCI spec that did not block /proc/scsi pathnames. The CVE describes availability impact from container access to /proc/scsi/scsi on older kernels. Public references include Moby PR #35399 and a related commit; the source bundle does not name a fixed release.

Likely exposure

Likely exposure is legacy Docker Moby deployments at or before 17.03.2-ce, especially on older Linux kernels where /proc/scsi behavior can affect storage devices. Modern container platforms may be unaffected, but validation should focus on old hosts and untrusted or multi-tenant container workloads.

Exploitation context

The source bundle does not show active exploitation, and the CVE is not in KEV. Exploitation requires specific environmental conditions and container access. The public description identifies the sensitive target path and impact, but does not provide evidence of widespread abuse.

Researcher notes

The CVE maps to CWE-200, though the described impact is availability loss through insufficient path blocking. Evidence is strongest for the vulnerable condition and Moby fix discussion; the provided sources do not establish active exploitation or a specific patched release.

Mitigation direction

  • Upgrade Docker Moby to a release that includes the /proc/scsi blocklist change.
  • Review Moby PR #35399 and vendor advisories for the exact fixed version.
  • Retire or update older Linux kernels on Docker hosts where feasible.
  • Avoid running untrusted containers on legacy Docker hosts.
  • Apply defense-in-depth controls limiting container access to host proc paths.

Validation and detection

  • Inventory Docker Moby versions and flag hosts running through 17.03.2-ce.
  • Identify Docker hosts using older Linux kernels.
  • Confirm the runtime default spec blocks /proc/scsi pathnames.
  • Review whether untrusted users can launch containers on flagged hosts.
  • Prioritize systems where storage availability is business-critical.
