CVE-2026-37526
7.8 · HIGHOverview
CVE-2026-37526 is a high-severity vulnerability affecting linuxfoundation automotive_grade_linux. It was published on May 1, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
AGL app-framework-binder (afb-daemon) through v19.90.0 allows any local process to execute privileged supervision commands (Exit, Do, Sclose, Config, Trace, Debug, Token, slist) without authentication via the abstract Unix socket @urn:AGL:afs:supervision:socket. The on_supervision_call function in src/afb-supervision.c dispatches all 8 commands without any credential verification. The abstract socket has no DAC protection, as acknowledged in the official CAUTION comment in src/afs-supervision.h. This allows a low-privileged local process to kill the daemon (DoS via Exit command), execute arbitrary API calls (via Do command), close arbitrary user sessions (via Sclose command), or leak the entire global configuration (via Config command). The vulnerability was introduced in commit b8c9d5de384efcfa53ebdb3f0053d7b3723777e1 on 2017-06-29.
Remediation
Check the references section for vendor advisories and patches from linuxfoundation. Update automotive_grade_linux to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
