Exploitation Conditions

Requires a locally-present malicious application capable of drawing an overlay (e.g., a SYSTEM_ALERT_WINDOW-style overlay) on top of a target window, exploiting faulty touch-occlusion handling in getTouchOcclusionMode so that occluded touches are not properly treated. Exploitation is bounded by several concrete limiting factors: the attacker must already have code running locally on the device (AV:L - this is not remotely reachable), the victim must actively interact with the manipulated/obscured UI (user interaction is explicitly required per the description), and the impact is limited to information disclosure (C:L) with no integrity or availability effect. The exact code path and precise overlay conditions that defeat the occlusion check are not detailed in the available sources beyond the component name.

Impact

This is a low-severity, locally-scoped issue that should be patched on a routine cycle rather than treated as an emergency, and the signals are largely consistent on that point. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, base 4.0) describes a local vector with limited confidentiality impact and no integrity or availability impact. EPSS is very low at 0.11% (1st percentile), there is no CISA KEV listing and no exploit or PoC reference in the supplied data, so exploitation is no public exploit identified at time of analysis. The vuln.today decision label is 'this_month', which aligns with the low EPSS and absence of active-exploitation signals - meaningful but not urgent. One internal conflict must be noted: the CVSS vector encodes UI:N (no user interaction) while the description explicitly states 'User interaction is needed for exploitation,' which is also inherent to a tapjacking/overlay attack; the description should be treated as authoritative here, so the UI:N in the vector appears understated - verify against the Android bulletin. Net: a genuine but low-priority tapjacking information-disclosure flaw, not a high-CVSS-but-overrated case because the CVSS is already low and matches the real-world picture.

Exploit ScenarioDerived

A user installs or already runs a malicious Android app that draws an overlay window on top of a sensitive system or app window. Because getTouchOcclusionMode does not correctly account for the occluding overlay, the user is induced to interact with (tap on) UI they cannot fully see, allowing the malicious app to glean information it should not have access to. No public exploit code is identified in the available data, and exploitation requires the victim to interact with the manipulated UI.

AnalysisAIv1 – Nov 03, 2026

Android 14 through Android 16 QPR2 and Android 17 contain a tapjacking/overlay flaw in getTouchOcclusionMode within WindowState.java that can leak limited information to a locally installed malicious app. Only a local app already running on the device can exploit it, and the victim must interact with the obscured UI; confidentiality impact is low with no integrity or availability effect, and EPSS is negligible at 0.11% (1st percentile). No CISA KEV listing or confirmed public exploit code is present in the available data, and the vendor bulletin (November 2026) is the patch reference.

RemediationAI

Apply the Android security update carrying the fix referenced in the 2026-11-01 Android Security Bulletin (https://source.android.com/docs/security/bulletin/2026/2026-11-01) and confirm the device's security patch level matches that bulletin, since the provided data does not enumerate a per-branch fixed build number. Until devices are updated, the exposure is reduced by limiting which apps can draw over other apps (review and revoke 'Display over other apps' / SYSTEM_ALERT_WINDOW permissions, which is the prerequisite capability for this tapjacking class), though that is a partial measure because the underlying occlusion handling remains unfixed. Patch on a routine monthly cycle rather than as an emergency: this is a local, low-confidentiality-impact issue with negligible EPSS and no KEV listing.

Technical ContextAI · show details

The issue lives in Android's window management layer: WindowState.java handles per-window state, and getTouchOcclusionMode decides how touches that pass through or land on a window should be treated when another window (such as an overlay drawn with SYSTEM_ALERT_WINDOW-style privileges) partially covers it. Faulty occlusion handling maps to CWE-451 (User Interface (UI) Misrepresentation of Critical Information), the classic tapjacking class, where a malicious overlay misrepresents what the user is tapping and the underlying window fails to reject or mark the obscured touch as untrusted. The result is local information disclosure only (C:L), reachable at AV:L with no additional execution privileges, and gated on user interaction. The sources do not specify the exact code path or the precise overlay geometry that defeats the occlusion check, so the trigger mechanics beyond the named method remain unconfirmed.
