Security readout for executives and security teams

CVE-2016-2440 is an Android Binder flaw that could let a malicious app gain higher privileges on affected devices. Business risk is mainly from old or unpatched Android phones, tablets, kiosks, or embedded devices. There is no provided evidence of active exploitation. Exposure is likely limited to legacy Android devices below the fixed versions or missing the 2016-05-01 Android security patch. Managed fleets with current patch levels are unlikely to be affected. Prioritize remediation for any legacy Android devices handling business data or exposed to app installation. This is an older local privilege-escalation issue, but unsupported Android endpoints can accumulate risk quickly. Mitigation focus: Update affected Android devices to the fixed versions or 2016-05-01 patch level or later.; Remove, replace, or isolate devices that cannot receive Android security updates.; Use enterprise controls to restrict untrusted app installation on legacy Android devices..
