CVE-2026-0091: High severity Google Android vulnerability

Affected Software

Remediation

Recommended actions to resolve this vulnerability, in priority order.

1. Remove

   Remove over-privileged shell user from your environment.

   If the shell user is not required, remove the account and any associated credentials from systems to eliminate the privilege source.

2. Configuration

   Remove unnecessary privileges from the over-privileged shell user: remove it from privileged groups, eliminate unnecessary sudoers entries, and remove setuid bits or elevated capabilities so the account cannot be used to execute code in privileged processes.

   shell user privileges = least-privilege (remove unnecessary elevated privileges)
3. Configuration

   Ensure the launcher process does not run with the shell user's elevated privileges. Run the launcher as a dedicated unprivileged account or drop privileges early during startup to prevent code execution via an over-privileged shell user.

   launcher process run_as_user = unprivileged user / drop privileges at startup
4. Compensating control

   Restrict access to local accounts and interactive shell access via host-based controls (SSH allowlists, PAM restrictions, limiting which accounts can log in, firewall/ACLs) and require strong authentication to reduce the risk of local exploitation.

5. Operational

   Audit system logs and account activity for signs of local code execution or privilege escalation; if compromise is suspected, isolate affected hosts, remediate, and rotate impacted credentials.
