CVE-2026-0010 Overview
CVE-2026-0010 is an out-of-bounds write vulnerability in the onTransact function of IDrmManagerService.cpp within Google Android. The vulnerability exists due to a missing bounds check, which could allow a local attacker to achieve privilege escalation without requiring any additional execution privileges or user interaction.
Critical Impact
This vulnerability enables local privilege escalation on affected Android devices through the DRM Manager Service, potentially allowing attackers to gain elevated system access without user interaction.
Affected Products
- Google Android 14.0
- Google Android 15.0
- Google Android 16.0

Technical Details for CVE-2026-0010
Vulnerability Analysis
This vulnerability (CWE-787: Out-of-bounds Write) resides in the Android DRM Manager Service, specifically within the onTransact handler of IDrmManagerService.cpp. The DRM Manager Service is a system-level component responsible for handling Digital Rights Management operations across the Android platform.
The flaw occurs when the service processes incoming binder transactions without properly validating the bounds of input data. When an attacker crafts a malicious transaction, the service writes data beyond the allocated buffer boundaries, corrupting adjacent memory regions.
Root Cause
The root cause of this vulnerability is a missing bounds check in the onTransact function of IDrmManagerService.cpp. When processing binder IPC transactions, the service fails to validate the size of incoming data against the allocated buffer capacity before performing write operations. This oversight allows malformed input to trigger memory corruption.
Attack Vector
The attack is local in nature, requiring the attacker to have local access to the device. The attacker can exploit this vulnerability by sending specially crafted binder transactions to the DRM Manager Service. Since no additional execution privileges are required and no user interaction is needed, a malicious application with minimal permissions could potentially exploit this flaw to escalate privileges to system level.
The out-of-bounds write can be leveraged to overwrite critical data structures or function pointers in adjacent memory, enabling arbitrary code execution with elevated privileges in the context of the DRM Manager Service process.
Detection Methods for CVE-2026-0010
Indicators of Compromise
- Unexpected crashes or restarts of the DRM Manager Service (drmserver)
- Anomalous binder transaction patterns targeting the DRM service
- Memory corruption signatures in system logs related to IDrmManagerService
- Unusual privilege escalation attempts from low-privilege applications
Detection Strategies
- Monitor for abnormal binder IPC activity targeting IDrmManagerService
- Implement kernel-level monitoring for memory corruption events in system services
- Deploy application behavior analysis to detect privilege escalation attempts
- Review system logs for DRM-related crashes or segmentation faults
Monitoring Recommendations
- Enable verbose logging for binder transactions on high-security devices
- Implement runtime application self-protection (RASP) for critical Android services
- Deploy endpoint detection solutions capable of monitoring Android system service behavior
- Regularly audit installed applications for suspicious DRM service interactions
How to Mitigate CVE-2026-0010
Immediate Actions Required
- Apply the March 2026 Android Security Bulletin patches immediately
- Restrict installation of applications from untrusted sources
- Ensure Google Play Protect is enabled and active on all devices
- Monitor device logs for signs of exploitation attempts
Patch Information
Google has addressed this vulnerability in the Android Security Bulletin March 2026. Device manufacturers and carriers should prioritize deploying the security update to affected devices running Android 14.0, 15.0, and 16.0. End users should check for and install available system updates through their device settings.
Workarounds
- Limit application installation to trusted sources such as Google Play Store
- Enable Google Play Protect for real-time threat scanning
- Consider implementing Mobile Device Management (MDM) solutions for enterprise environments
- Restrict device access to trusted users until patches are applied
# Check Android security patch level
adb shell getprop ro.build.version.security_patch
# Verify current Android version
adb shell getprop ro.build.version.release
# Monitor DRM service status
adb shell dumpsys drm
