CVE-2026-13196

Kernel memory corruption via unchecked process-image offsets

Published Aug 14, 2026 · Updated Aug 14, 2026

Out-of-bounds write in KUNBUS piControl 2.6.2 and earlier allows local users to corrupt kernel memory via crafted device data. Process-image management accepts out-of-range offsets from crafted configuration and writes attacker-controlled data beyond the process-image buffer. The attack requires local authentication and device configuration access; successful exploitation corrupts adjacent kernel memory and causes denial of service.
