CVE-2026-0108 Overview
CVE-2026-0108 is an improper access control vulnerability affecting the PowerVR GPU component in Google Android. The register protection of the PowerVR GPU is incorrectly configured, which could allow a local attacker to disclose sensitive information without requiring additional execution privileges. User interaction is not needed for exploitation, making this a passive attack vector that can be exploited by malicious applications running on the device.
Critical Impact
Local information disclosure vulnerability in PowerVR GPU that requires no user interaction and no special privileges to exploit, potentially exposing sensitive GPU memory contents.
Affected Products
- Google Android (all versions prior to March 2026 security patch)
- Android devices utilizing PowerVR GPU hardware
- Google Pixel devices (see Pixel-specific security bulletin)

Technical Details for CVE-2026-0108
Vulnerability Analysis
This vulnerability stems from an improper access control issue (CWE-284) in the PowerVR GPU driver's register protection mechanism. The GPU registers, which should be protected from unauthorized access, are incorrectly configured, allowing unprivileged local processes to read sensitive information stored in GPU memory or registers.
The PowerVR GPU architecture relies on proper register access controls to isolate different processes and protect sensitive data processed by the GPU. When these controls are misconfigured, a malicious application can potentially access GPU registers that should be restricted, leading to information disclosure. This type of vulnerability is particularly concerning in mobile environments where sensitive data such as cryptographic operations, secure rendering, or biometric processing may occur on the GPU.
The local attack vector means an attacker would need to execute code on the target device, typically through a malicious application. However, once code execution is achieved, no additional privileges or user interaction are required to exploit this vulnerability.
Root Cause
The root cause of CVE-2026-0108 is an improper access control configuration (CWE-284) in the PowerVR GPU driver. The register protection mechanism that should restrict access to sensitive GPU registers was not correctly implemented, failing to enforce proper access boundaries between privileged and unprivileged contexts. This allows unauthorized read access to protected GPU memory regions.
Attack Vector
The attack vector is local, requiring an attacker to have code execution capability on the target Android device. This is typically achieved through:
- Installing a malicious application on the device
- Compromising an existing application to execute malicious code
- Exploiting another vulnerability to gain initial code execution
Once code execution is established, the attacker can directly access the misconfigured GPU registers without requiring elevated privileges or user interaction. The attack can be performed silently in the background, making detection difficult for end users.
The vulnerability allows reading of protected register contents, which may contain residual data from other applications' GPU operations, potentially including sensitive information such as rendered content, cryptographic material, or other processed data.
Detection Methods for CVE-2026-0108
Indicators of Compromise
- Unusual GPU register access patterns from unprivileged applications
- Applications attempting to directly interface with GPU hardware registers outside normal rendering APIs
- Anomalous memory access patterns targeting GPU-related kernel drivers
- Presence of known malicious applications exploiting PowerVR vulnerabilities
Detection Strategies
- Monitor for applications accessing /dev/pvr* or similar GPU device nodes with unexpected access patterns
- Implement runtime application security monitoring to detect unusual GPU driver interactions
- Deploy mobile threat detection solutions capable of identifying applications attempting to exploit GPU vulnerabilities
- Analyze installed applications for known exploitation techniques targeting PowerVR GPU
Monitoring Recommendations
- Enable Android's built-in security logging to capture GPU driver access attempts
- Deploy endpoint detection and response (EDR) solutions on managed mobile devices
- Monitor for security bulletins and patch compliance across the Android device fleet
- Implement application vetting processes to identify potentially malicious applications before deployment
How to Mitigate CVE-2026-0108
Immediate Actions Required
- Apply the Android Security Patch Level 2026-03-01 or later immediately
- Ensure automatic security updates are enabled on all Android devices
- Review installed applications and remove any untrusted or suspicious applications
- For enterprise environments, verify patch deployment through mobile device management (MDM) solutions
Patch Information
Google has addressed this vulnerability in the March 2026 Android Security Bulletin. The fix is included in the security patch level 2026-03-01. Organizations and users should update their devices to this patch level or later to remediate the vulnerability.
For detailed patch information, refer to the following official resources:
Workarounds
- Limit installation of applications to trusted sources only (Google Play Store with Play Protect enabled)
- Enable Google Play Protect to scan for potentially harmful applications
- For high-security environments, consider restricting device usage until patches can be applied
- Implement network-level monitoring to detect potential data exfiltration from compromised devices
# Verify Android security patch level on device
adb shell getprop ro.build.version.security_patch
# Expected output: 2026-03-01 or later
# Check for pending system updates via ADB
adb shell am start -a android.settings.SYSTEM_UPDATE_SETTINGS
