CVE-2026-56970

Google · Android

A missing permission check in the Android kernel allows local attackers to achieve escalation of privilege without requiring user interaction or elevated execution privileges.

Executive summary

A critical privilege escalation vulnerability in the Google Android kernel enables unauthenticated local attackers to gain elevated access to the device.

Vulnerability

The flaw is an elevation of privilege vulnerability caused by a missing permission check in multiple locations within the Android kernel. This allows an unauthenticated local attacker to bypass security controls and gain unauthorized privileges on the target system.

Business impact

The ability for a local attacker to escalate privileges to the kernel level poses a severe risk to device integrity and data confidentiality. With full access to the operating system kernel, an attacker could potentially bypass all security sandboxes, exfiltrate sensitive user data, or install persistent malware. Given the CVSS score of 8.4, this vulnerability is classified as High severity and requires immediate attention to prevent total system compromise.

Remediation

Immediate Action: Apply the latest security updates provided by Google or your specific Android device manufacturer as soon as they become available.

Proactive Monitoring: Monitor system logs for unusual privilege escalation attempts or unexpected kernel-level activities that indicate unauthorized access.

Compensating Controls: Ensure that device security policies are strictly enforced, including the restriction of sideloaded applications and the use of managed device profiles to limit the attack surface.

Exploitation status

Public Exploit Available: No

Analyst recommendation

Organizations and individual users should treat this vulnerability with high priority due to the potential for complete system compromise. Administrators must monitor vendor security bulletins and deploy the relevant kernel patches to all managed Android devices immediately upon release.
