AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local execution with low privileges is sufficient; no scope change since impact is bounded to device user-space; full C/I/A reflects cross-profile data access potential.

In setClipboardAccessNotificationsEnabledForUser of ClipboardService.java, there is a possible mult-iuser isolation 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
Multi-user isolation breaks in Android's ClipboardService framework layer (CWE-284 Improper Access Control) across Android 14 through 17, enabling a locally-executed low-privileged process to cross user-profile boundaries and escalate privileges with full confidentiality, integrity, and availability impact. The logic error in setClipboardAccessNotificationsEnabledForUser fails to correctly enforce per-user access checks, allowing one user context to manipulate clipboard access notification state for other user profiles on the same device. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a malicious application with code execution capability running under a low-privileged Android user account (PR:L) on a device with Android 14, 15, 16, 16-qpr2, or 17. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 7.8 with a local attack vector (AV:L), low attack complexity (AC:L), low privilege requirement (PR:L), and no user interaction (UI:N) accurately characterizes this as a local privilege escalation requiring only an installed app running under an unprivileged user account. … 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 September 2026 Android Security Patch Level (SPL: 2026-09-01) as documented in the Android Security Bulletin at https://source.android.com/docs/security/bulletin/2026/2026-09-01 for Android 14, 15, 16, 16-qpr2, and 17. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: audit your inventory to identify Android 14-17 devices, particularly those with multi-user profiles or handling sensitive data. …
