CVE-2026-37525 · Severity: high · CVSS 7.8 · Published 2026-05-01

Automotive Grade Linux (AGL) uses a component called the app-framework-binder to manage communication between different automotive applications. A security flaw in this component allows a low-privileged local application to bypass security checks and execute commands with higher system privileges. This could allow an attacker to gain unauthorized control over sensitive vehicle functions or access restricted system data.

## Technical details

A privilege escalation vulnerability exists in the afb-daemon component of Automotive Grade Linux (AGL) due to improper credential management in the supervision 'Do' command. The function 'on_supervision_call' in 'src/afb-supervision.c' explicitly nullifies request credentials by calling 'afb_context_change_cred' with a NULL value before dispatching an attacker-controlled API call. Because the attacker controls both the 'api' and 'verb' parameters via JSON input, they can invoke any registered API. If the target API relies on the credential context for authorization decisions, it may 'fail open' when encountering the NULL credentials, allowing a local low-privileged process to execute privileged operations.
