CVE-2026-13197

Local denial of service via configuration reset race

Published Aug 14, 2026 · Updated Aug 14, 2026

Race condition in KUNBUS piControl 2.6.2 allows local users to corrupt kernel memory and interrupt service through concurrent device requests. The configuration-reset path races with concurrent process-image management, allowing kernel configuration objects to be freed while another request still dereferences them. A local authenticated session with access to the piControl character device is required, and exploitation causes invalid pointer dereferences and denial of service.
