CVE-2026-50211: Exposed Factory Testing App Boundaries
Leftover engineering diagnostics and factory-level diagnostic software remain exposed on retail builds, giving malicious apps write privileges to internal NVRAM registers.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Remove
Remove
factory-level diagnostic softwarefrom your environment.Uninstall or remove leftover engineering and factory diagnostic applications from retail builds if they are not required.
- Configuration
Disable engineering diagnostics and factory-level diagnostic software on retail builds to remove exposed testing app boundaries and interfaces.
retail build (factory diagnostic interfaces) factory_diagnostics_enabled = false - Configuration
Restrict write privileges to internal NVRAM registers so that only trusted, privileged or signed system components can perform writes; deny write access to third-party/untrusted apps.
internal NVRAM write_privileges = restricted to privileged/signed system components - Compensating control
Apply platform access controls (for example via MDM, application sandboxing, or OS-level policy enforcement) to block untrusted apps from reaching diagnostic interfaces or NVRAM until the diagnostic software is removed or disabled.
