AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local attack vector with low-privilege installed app; no user interaction; overlay bypass enables full device CIA impact within unchanged scope.
Primary rating from Vendor (android).
CVSS VectorVendor: android
Lifecycle Timeline
5DescriptionCVE.org
In setHiddenWhileSuspended of WindowState.java, there is a possible overlay 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
Local privilege escalation in Android's Window Manager Service (WindowState.java) allows a low-privileged app to bypass overlay protection mechanisms across Android versions 14 through 17. The logic error in setHiddenWhileSuspended permits unauthorized overlay windows to remain visible or interact with the display even when they should be hidden for suspended apps, creating a pathway to full CIA compromise on the device. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a low-privileged application to be installed and executable on the target Android device (PR:L, AV:L) - this is the foundational prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) accurately reflects a locally exploitable privilege escalation requiring only a low-privileged installed app and no user interaction, with full CIA impact - even a mid-sized municipal IT team in kalisz managing a large Android device fleet should treat this as a meaningful internal threat given that malicious or compromised apps could silently escalate without any prompt. … 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 Bulletin patches available at https://source.android.com/docs/security/bulletin/2026/2026-09-01; exact patch build numbers should be confirmed from the bulletin and applied via OTA update or vendor-specific firmware channels. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct a comprehensive audit of all organizational and employee-owned Android devices to identify those running affected versions (Android 14 through 17), and document device inventory, data classification, and business criticality. …
