Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SI-10 Information Input Validation
addresses: CWE-73

Rejects externally supplied file or resource identifiers that fail validity checks.

SI-22 Information Diversity
addresses: CWE-610

Limits impact of an externally controlled reference to a primary information resource by switching to an identified alternative.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-610, a class-level weakness, and none of its children carries one either.
