Exploitation Conditions

Exploitation requires local access to the device (AV:L) and a low-privileged application installed on an affected Android version - Android 14, 15, 16, or 16-QPR2 (PR:L per CVSS vector). No user interaction is required (UI:N). Because the flaw resides across multiple functions of AppOpsService.java with no specific feature toggle or non-default configuration cited as a prerequisite, any affected Android device with a locally running low-privileged application satisfies the conditions. What limits exploitation: the attack is strictly local-scope (AV:L, S:U) - remote network exploitation is not possible; the impact is confined to information disclosure only (C:L, I:N, A:N), meaning an attacker gains read access to protected data but cannot modify system state or cause a denial of service; and the attacker must already have code executing on the device as a low-privileged app, ruling out purely passive or drive-by attack paths.

Impact

CVSS 3.3 (Low) with vector AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N reflects a local-only attack surface requiring a low-privileged caller, with limited confidentiality impact and no integrity or availability consequences. SSVC corroborates low urgency: exploitation status is none, the attack is not automatable (no remote vector exists), and technical impact is only partial. No EPSS score was provided in the input data - this gap should be noted when prioritizing against other Android bulletin items. The absence of a CISA KEV listing and any identified POC code means this vulnerability is not being actively or opportunistically exploited at time of analysis. Real-world risk is limited to scenarios where a malicious or trojanized local application attempts to harvest protected App Ops information - relevant for threat models involving sideloaded apps or compromised devices, but not a critical priority compared to remote or unauthenticated vulnerabilities in the same bulletin cycle.

Exploit ScenarioDerived

A locally installed application with low privileges on an affected Android 14-16 device calls vulnerable functions in AppOpsService without the expected permission enforcement being applied, allowing it to read protected system or user information - such as App Ops state or usage data for other applications - that should be inaccessible. No public proof-of-concept code has been identified at time of analysis, limiting immediate exploitation risk. The attack requires physical or logical access to the device with at least a user-installed application context, confining the threat primarily to trojanized apps or insider-access scenarios.

AnalysisAIv1 – Jun 02, 2026

Android's AppOpsService (AppOpsService.java) exposes protected system or user information to low-privileged local applications due to missing permission checks across multiple functions, enabling unauthorized information disclosure without requiring additional execution privileges. Affected versions span Android 14 through Android 16-QPR2, representing a broad swath of active Android deployments in use today. No public exploit code exists and no active exploitation has been confirmed (not in CISA KEV); SSVC rates exploitation as none with only partial technical impact, placing this at low urgency for most organizations.

RemediationAI

Apply patches distributed through the Android Security Bulletin dated June 1, 2026, available at https://source.android.com/docs/security/bulletin/2026/2026-06-01. Device manufacturers (OEMs) are responsible for distributing these patches via over-the-air updates; users and administrators should ensure managed devices are updated to the June 2026 Android security patch level or later. No exact patched build version string beyond the security patch level date is independently confirmed from available input data - verify the specific SPL string with your OEM. As a compensating control, enforcing mobile device management (MDM) policies that restrict sideloading and limit installation to trusted application sources (Google Play with Play Protect enabled) directly reduces the attack surface, since exploitation requires a locally installed low-privileged application. This mitigation carries the trade-off of restricting enterprise app distribution workflows that rely on sideloading.

Technical ContextAI · show details

AppOpsService.java is a core Android framework component responsible for enforcing the App Operations (AppOps) permission system - the runtime layer that governs whether applications may access sensitive capabilities such as location, microphone, camera, and usage statistics. CWE-269 (Improper Privilege Management) identifies the root cause: multiple functions within this service fail to enforce the expected permission checks, allowing callers with only low-level privileges to invoke them and receive protected information they should be denied. The affected CPE (cpe:2.3:a:google:android:*:*:*:*:*:*:*:*) confirms broad platform-level impact. Per ENISA EUVD-2026-33815, the affected branches are Android 14, Android 15, Android 16, and Android 16-QPR2, indicating the flaw was introduced or carried forward across multiple major release lines.

DescriptionCVE.org

In multiple functions of AppOpsService.java, there is a possible missing permission check due to a permissions bypass. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

Attack Technique

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
