CVE-2026-55359

Google · Android

A logic error in the Android kernel allows for a local privilege escalation, enabling an authenticated user to gain elevated system permissions without requiring user interaction.

Executive summary

A high-severity logic error in the Google Android kernel permits local privilege escalation, posing a significant risk of unauthorized system access.

Vulnerability

The vulnerability is an elevation of privilege flaw caused by a logic error within the Android kernel. An attacker with standard user execution privileges can exploit this flaw to bypass permission controls without any requirement for user interaction.

Business impact

Successful exploitation of this vulnerability allows a local attacker to escalate their privileges, potentially gaining full control over the affected device. This could lead to a total compromise of sensitive user data, unauthorized execution of system commands, and the complete bypass of security policies. With a CVSS score of 7.8, this vulnerability represents a high risk to organizational security, particularly in environments where multi-user access or shared device usage is prevalent.

Remediation

Immediate Action: Monitor the official Google Android Security Bulletin for the release of a security patch and apply it to all managed devices immediately upon availability.

Proactive Monitoring: Review system logs for signs of unauthorized process execution or unexpected privilege changes that may indicate exploitation attempts by local users.

Compensating Controls: Enforce strict application sandboxing and restrict the installation of untrusted or third-party applications to minimize the attack surface available to local users.

Exploitation status

Public Exploit Available: Unknown

Analyst recommendation

Given the high severity of this kernel-level vulnerability, organizations must prioritize the deployment of upcoming security updates from Google. While there is no current evidence of active exploitation, the ability for a local user to escalate privileges provides a critical foothold for further malicious activity. Administrators should prepare to patch all Android endpoints as soon as the vendor releases the necessary firmware or security module updates.
