CVE-2026-102125

Security attributes enable correct sphere assignment and subsequent enforcement decisions.

Access enforcement directly requires approved authorizations to be applied to compartmentalized resources.

Information flow enforcement structurally prevents unauthorized mixing of data or functions across privilege boundaries.

Separation of duties forces distinct privilege compartments for critical operations.

Least privilege directly limits each process or user to only the compartments it needs.

Explicit separation of user and management functionality implements the required compartmentalization.

Least-privilege policy directly enforces separation of privilege levels and access rights.

Network and environment segmentation implements the isolation required to prevent unauthorized cross-compartment access.

Access control policies establish the boundaries that isolation must enforce.

Managing access rights is the operational mechanism for compartmentalizing privileges.

A.5.3 directly mandates determining and enforcing segregation of conflicting duties/roles (with examples that map to privilege boundaries), which stops improper isolation from being exploitable in most cases; the bounded remainder is small organizations or cases where segregation is impracticable and the clause itself falls back to other controls.

Privileged access rights require strict isolation from ordinary user contexts.

A.8.22's network-domain segregation and perimeter gateways (firewalls) directly enforce isolation between trust/criticality levels, stopping cross-domain exploitation of improper compartmentalization for the bulk of network-based privilege flows; the bounded remainder is non-network resources (e.g. process-level or in-memory compartmentalization inside a single domain).

A.8.27 mandates security-by-design principles including least privilege, defense-in-depth, compartmentalization via zero-trust/never-trust, fail-secure, and explicit analysis of control placement and integration to isolate differing privilege levels; this stops exploitation of most improper-isolation cases but leaves a bounded remainder (e.g. certain legacy or safety-overriding exceptions that must be formally acknowledged).
