Lifecycle Timeline
5DescriptionCVE.org
In multiple functions of RemoteViews.java, there is a possible background activity launch bypass due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Background activity launch bypass in Android's RemoteViews framework allows a locally installed malicious application with basic user privileges to escalate to full device compromise without user interaction. Multiple functions in RemoteViews.java contain a logic error (CWE-693) that defeats Android's background activity launch (BAL) protection mechanism, enabling unprivileged apps to launch foreground activities from background context. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a malicious Android application to be installed and running on the target device, granting basic user-level execution context (PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) accurately captures the local nature of exploitation: an attacker must have a malicious app installed on the target device (PR:L), but once present, exploitation requires no user interaction and no elevated permissions. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Android security patch released in the September 2026 Android Security Bulletin (https://source.android.com/docs/security/bulletin/2026/2026-09-01). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory all devices running Android 14, 15, 16, 16-QPR2, or 17; configure Mobile Device Management policies to restrict app installation to official app stores only and disable sideloading. …
