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.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
