Mitigating Controls
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.
Maintaining currency with technologies and practices reduces selection of encryption mechanisms that provide inadequate strength.
Updated assessments identify when previously adequate encryption strength no longer meets current attack capabilities or compliance drivers.
Establishment procedures require selection and generation of keys with adequate length and strength for the chosen algorithm.
Specifies required cryptography types and parameters, preventing selection of inadequate encryption strength.
Prompt patching corrects inadequate encryption strength when vendors release updates that increase key sizes or algorithm security.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Requiring the organization to define and enforce minimum cryptographic strength prevents deployment of insufficient key lengths or weak ciphers that can be brute-forced.
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-326, a class-level weakness. Rules are authored against its narrower children: CWE-328.
