The non-existent notification listener vulnerability was introduced in the initial Android 5.0.2 builds for the Samsung Galaxy S6 Edge devices, but the vulnerability can persist on the device even after the device has been upgraded to an Android 5.1.1 or 6.0.1 build. The vulnerable system app gives a non-existent app the ability to read the notifications from the device, which a third-party app can utilize if it uses a package name of com.samsung.android.app.portalservicewidget. This vulnerability allows an unprivileged third-party app to obtain the text of the user's notifications, which tend to contain personal data.

Security readout for executives and security teams

Some Samsung Galaxy S6 Edge devices may retain a flawed notification permission after upgrades. A normal app could abuse that leftover trust to read notification text, which often includes messages, one-time codes, calendar details, or other personal data. Exposure appears limited to Samsung Galaxy S6 Edge devices with the affected build history. The source bundle does not identify broader Android models, enterprise MDM indicators, or complete patched-version boundaries. Treat this as a privacy and mobile-fleet hygiene issue. Prioritize regulated users, executives, and BYOD fleets where notification content may expose credentials, customer data, or sensitive communications. Mitigation focus: Check Samsung or carrier guidance for confirmed remediation steps.; Do not rely on OS upgrade alone for affected devices.; Restrict installation of untrusted third-party apps on legacy devices..
