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.

addresses: CWE-300

Ensures only authenticated endpoints can access the communication channel, blocking unauthorized non-endpoint access.

addresses: CWE-300

Physically restricts transmission channels so they cannot be accessed or tapped by non-endpoint actors within facilities.

addresses: CWE-300

Periodic TSCM surveys identify unauthorized access points or taps that make communication channels reachable by non-endpoint adversaries.

addresses: CWE-300

Explicitly isolates the communications path so it cannot be accessed or intercepted by non-endpoint entities during security functions.

addresses: CWE-300

Restrictions and channel controls reduce the chance that VoIP media or signaling streams remain accessible to non-participants.

addresses: CWE-300

Directly prevents non-endpoint access or interception of the session communication path.

addresses: CWE-300

An out-of-band channel is inaccessible to non-endpoints that can observe or interfere with the primary communication channel.

addresses: CWE-300

The control restricts an inherently broadcast wireless channel to only intended endpoints, mitigating accessibility by non-endpoints.

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.

blocks

A.5.14 mandates rules/procedures/agreements (incl. recipient auth, crypto per 8.24, stronger auth on public nets, anti-interception/unauth-access controls) that stop non-endpoint actors from accessing/influencing the channel for most transfer forms; remainder (e.g. some verbal transfer, misrouting not caught by auth) is nameable.

degrades

Network security controls directly address channel integrity and endpoint authentication.

degrades

Security of network services includes measures to verify endpoints and protect channel integrity.

blocks

Cryptography provides channel integrity and can support endpoint authentication.

blocks

Secure authentication mechanisms verify actor identity at both ends of the channel.

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-300, a class-level weakness, and none of its children carries one either.
