CVE-2026-9030

A denial-of-service vulnerability exists in httpd service on Archer A6 v4 where the asynchronous systool instruction handlng path in httpd does not properly synchronize or safely manage concurrent systool operations. By sending crafted systool instructions through the asynchronous request path, successful exploitation may cause the httpd process or device management service to crash and may result in temporary loss of access to the web management interface or device reboot.
