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.

addresses: CWE-326

Maintaining currency with technologies and practices reduces selection of encryption mechanisms that provide inadequate strength.

addresses: CWE-326

Updated assessments identify when previously adequate encryption strength no longer meets current attack capabilities or compliance drivers.

addresses: CWE-326

Establishment procedures require selection and generation of keys with adequate length and strength for the chosen algorithm.

addresses: CWE-326

Specifies required cryptography types and parameters, preventing selection of inadequate encryption strength.

addresses: CWE-326

Prompt patching corrects inadequate encryption strength when vendors release updates that increase key sizes or algorithm security.

PR.DS-01 partial match
blocks

Proper cryptographic hashing for data-at-rest directly prevents trivial password encoding while the control addresses broader data protection needs.

degrades

Requires secure handling and protection of authentication information, directly addressing weak password encoding.

blocks

Requires appropriate use of cryptography, indirectly discouraging weak encoding schemes.

prevents

Enforces secure coding practices that would reject trivial password encoding.

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.
