DescriptionCVE.org

Improper export of android application components in OmaCP prior to SMR May-2026 Release 1 allows local attackers to trigger privileged functions.

AnalysisAI

OmaCP on Samsung Android devices (Android 14, 15, and 16) exposes improperly exported application components that allow any co-resident local application to invoke privileged functions without holding the required permissions. The flaw is rooted in Android's IPC mechanism, where components lacking proper access control declarations can be targeted by crafted intents from other installed apps. No public exploit code has been identified at the time of analysis, and EPSS sits at 0.01% (3rd percentile), consistent with SSVC's exploitation status of none; risk is real but bounded by the local attack vector.

Technical ContextAI

OmaCP is a Samsung Mobile application implementing OMA (Open Mobile Alliance) Client Provisioning, used to push and apply carrier-side device configuration - a function with access to sensitive provisioning operations. Android application components (Activities, Services, BroadcastReceivers, ContentProviders) may be declared as exported via android:exported='true' or by including an intent-filter without an android:permission guard, making them reachable by any app on the device. Without proper permission enforcement on these components, a malicious co-resident app can dispatch crafted intents to trigger privileged provisioning or configuration functions. This vulnerability class maps to CWE-926 (Improper Export of Android Application Components), though no CWE is formally assigned in the NVD entry. The CPE is cpe:2.3:a:samsung_mobile:samsung_mobile_devices:*:*:*:*:*:*:*:*, and the 'Google' tag suggests coordinated disclosure potentially involving Android's security team.

RemediationAI

Apply Samsung's SMR May-2026 Release 1, which patches the improper component export in OmaCP for Android 14, 15, and 16. Device owners should verify the May 2026 security patch level is applied via Settings > Software Update or Settings > About Phone > Software Information. Enterprise administrators managing Samsung fleets should confirm patch deployment through their Mobile Device Management (MDM) solution. As a compensating control before patching, restrict installation of untrusted third-party applications using MDM policies or Google Play Protect enforcement - this reduces the likelihood of a malicious app being present to exploit the exported component, though it does not eliminate the underlying flaw.
