CVE-2026-0106
π TL;DR
This vulnerability allows local attackers to map arbitrary memory addresses due to missing bounds checking in the vpu_mmap function. This can lead to local privilege escalation without requiring user interaction. Affects Android devices with vulnerable VPU drivers.
π» Affected Systems
- Android devices with VPU drivers
β οΈ Risk & Real-World Impact
Worst Case
Complete system compromise with root privileges, allowing attackers to install persistent malware, access all user data, and control device functions.
Likely Case
Local privilege escalation enabling unauthorized access to sensitive data and system resources from a compromised user context.
If Mitigated
Limited impact if proper SELinux policies and kernel hardening are in place, potentially containing the escalation within sandboxed environments.
π― Exploit Status
Requires local access but no user interaction. Exploitation involves crafting specific ioctl calls to trigger the vulnerable mmap operation.
π οΈ Fix & Mitigation
β Official Fix
Patch Version: February 2026 Android Security Patch
Vendor Advisory: https://source.android.com/security/bulletin/pixel/2026-02-01
Restart Required: Yes
Instructions:
1. Check for system updates in Settings > System > System update. 2. Install February 2026 security patch. 3. Reboot device to apply kernel updates.
π§ Temporary Workarounds
Restrict VPU driver access
linuxLimit access to VPU device nodes using SELinux policies or file permissions
chmod 600 /dev/vpu*
chown root:root /dev/vpu*
π§― If You Can't Patch
- Implement strict application sandboxing and SELinux policies to limit damage from privilege escalation
- Monitor for unusual process behavior and privilege escalation attempts using security monitoring tools
π How to Verify
Check if Vulnerable:
Check Android security patch level in Settings > About phone > Android version. If before February 2026, device is vulnerable.Check Version:
adb shell getprop ro.build.version.security_patchVerify Fix Applied:
Verify security patch level shows 'February 1, 2026' or later in Settings > About phone > Android version.π‘ Detection & Monitoring
Log Indicators:
- Unusual ioctl calls to /dev/vpu devices
- Process privilege escalation from user to root context
- Kernel crash logs related to memory mapping
Network Indicators:
- None - this is a local vulnerability
