CVE-2026-87913

Associating ownership as a security attribute enables subsequent verification of resource ownership.

Requiring access decisions to consider all relevant attributes includes ownership verification.

A reference monitor provides the tamperproof mechanism that can enforce ownership checks.

Access enforcement directly requires verifying ownership before granting access to resources.

Authenticator management requires generation and distribution of values that cannot be derived from observable state.

Cryptographic key establishment mandates use of unpredictable, non-observable values for keys and nonces.

Enforcing defined access permissions and authorizations directly prevents missing ownership verification for resources.

Hardened configuration baselines can enforce use of cryptographically secure RNG sources and disable predictable state-based mechanisms.

Secure SDLC practices directly require cryptographically secure random values instead of observable state such as time or PID.

Access control policies can require ownership verification before granting access to critical resources.

Identity management processes can include verification of resource ownership during provisioning and access decisions.

A.5.18 governs the provisioning, review, and revocation of access rights based on authorization and policy; it does not verify resource ownership and cannot stop exploitation of unverified ownership.

A.8.2 controls the allocation, review, expiry and use of privileged rights via authorization and least-privilege rules; it has no bearing on whether a resource's ownership is verified before use, so the CWE-283 weakness can still be present and exploited.

Cryptographic controls replace predictable values with high-entropy, non-guessable material.
