CVE-2026-0197 Overview
CVE-2026-0197 is an information disclosure vulnerability in the Video Processing Unit (VPU) component addressed in the Android Security Bulletin for September 2026. A logic error in the VPU code allows a local attacker with System-level execution privileges to read sensitive information that should be isolated. Exploitation does not require user interaction. The issue is tracked under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor.
Critical Impact
A local actor holding System privileges can obtain sensitive data processed or handled by the VPU, undermining confidentiality boundaries between components on the device.
Affected Products
- Android devices covered by the Android Security Bulletin September 2026
- Pixel devices referenced in the September 2026 Pixel Update Bulletin
- Any downstream Android builds incorporating the affected VPU component

Technical Details for CVE-2026-0197
Vulnerability Analysis
The vulnerability resides in the Video Processing Unit (VPU) subsystem. A logic error in the code path permits sensitive data to be exposed to a caller that should not have access to it. Because the flaw is a logic issue rather than a memory-safety defect, exploitation does not depend on corrupting memory or bypassing exploit mitigations.
The attack is local. The caller must already possess System execution privileges on the device. Successful exploitation yields disclosure of information handled by the VPU, without impact to integrity or availability. No user interaction is required, which means a malicious privileged process can trigger the disclosure silently.
Root Cause
The root cause is a logic error inside the VPU code that fails to properly restrict what data is returned or accessible through an interface reachable from privileged system context. The condition is classified as [CWE-200], indicating that the code exposes information to an actor that is not authorized to receive it. Full component-level details are described in the Android Security Bulletin September 2026.
Attack Vector
An attacker first needs code execution with System privileges on the target Android device. From that context, the attacker invokes the affected VPU interface in a way that triggers the flawed logic branch and returns data that should have remained inaccessible. Because no user interaction is required, the primitive is well suited to chaining with other issues in a privilege-escalation or data-exfiltration path.
No public proof-of-concept, exploit code, or in-the-wild exploitation has been reported. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The current EPSS probability is 0.077%.
Detection Methods for CVE-2026-0197
Indicators of Compromise
- No public indicators of compromise have been published for CVE-2026-0197.
- Presence of an Android build fingerprint predating the September 2026 security patch level on a managed device.
- Unexpected privileged processes interacting with VPU device nodes or vendor HAL services.
Detection Strategies
- Inventory Android endpoints and flag any device whose reported security patch level is earlier than 2026-09-01.
- Monitor mobile device management (MDM) compliance reports for devices missing the September 2026 update.
- Correlate crash and audit logs from vendor VPU services for anomalous access patterns from System-context processes.
Monitoring Recommendations
- Enforce patch-level attestation through MDM or zero-trust access policies before granting sensitive resources to Android clients.
- Track new advisories referenced in the Android Security Bulletin September 2026 for related VPU issues.
- Review installed third-party applications on privileged or rooted devices, since a System-level foothold is a prerequisite for exploitation.
How to Mitigate CVE-2026-0197
Immediate Actions Required
- Apply the September 2026 Android security patch level (2026-09-01 or later) to all affected devices as soon as vendor updates are available.
- Prioritize patch deployment on devices used by administrators, developers, and executives who handle sensitive data.
- Audit devices for unauthorized System-privileged software or signs of rooting that could satisfy the exploitation prerequisite.
Patch Information
Google addressed the issue in the September 2026 Android Security Bulletin. Fix details, component attribution, and Pixel-specific updates are published in the Android Security Bulletin September 2026. Original equipment manufacturers ship the corresponding patch through their standard monthly update channels.
Workarounds
- No vendor-provided workaround exists; patching to the September 2026 security patch level is the supported remediation.
- Restrict installation of applications that request or require elevated privileges to reduce the likelihood of a System-context foothold.
- Enforce MDM policies that block or quarantine devices unable to reach the required patch level.
