cipso_v4_validate in include/net/cipso_ipv4.h in the Linux kernel before 3.11.7, when CONFIG_NETLABEL is disabled, allows attackers to cause a denial of service (infinite loop and crash), as demonstrated by icmpsic, a different vulnerability than CVE-2013-0310.

Security readout for executives and security teams

Plain-English summary

CVE-2013-7470 is an older Linux kernel denial-of-service flaw. Under a specific kernel configuration, specially formed network traffic could trigger an infinite loop and crash the system. The sources do not indicate data theft, privilege escalation, or active exploitation.

Executive priority

Prioritize remediation where old Linux kernels support production, network-facing, or high-availability services. This is not evidenced as actively exploited, but a kernel crash can still cause business disruption on exposed legacy infrastructure.

Technical view

The issue affects cipso_v4_validate in include/net/cipso_ipv4.h in Linux kernels before 3.11.7 when CONFIG_NETLABEL is disabled. The CVE describes denial of service through infinite loop and crash, with a Linux fix referenced by commit f2e5ddcc0d12f9c4c7b254358ad245c9dddce13b and ChangeLog-3.11.7.

Likely exposure

Likely exposure is limited to systems or appliances using Linux kernels before 3.11.7 with CONFIG_NETLABEL disabled. The source bundle does not provide complete affected product or CPE data, so downstream vendor advisories should be checked for product-specific exposure.

Exploitation context

The CVE says the crash was demonstrated by icmpsic, but the provided sources do not show confirmed active exploitation. CISA KEV status is false in the bundle, so treat this as a stability and availability risk unless vendor evidence says otherwise.

Researcher notes

Evidence is concise and old. The core condition is Linux before 3.11.7 plus CONFIG_NETLABEL disabled. The record distinguishes this from CVE-2013-0310. No CVSS, CWE, comprehensive affected-product list, or exploit-in-the-wild source is included.

Mitigation direction

  • Upgrade affected Linux kernels to 3.11.7 or a vendor-supported fixed build.
  • Review F5 and Arista advisories for product-specific applicability and remediations.
  • Identify unsupported legacy Linux systems and prioritize retirement or isolation.
  • If no vendor fix is confirmed, request current guidance from the vendor.

Validation and detection

  • Inventory Linux kernel versions across servers, appliances, and embedded platforms.
  • Check whether CONFIG_NETLABEL is disabled on potentially affected systems.
  • Map appliances against F5, Arista, and other vendor security advisories.
  • Confirm patch status against the Linux 3.11.7 changelog or vendor release notes.
