CVE-2026-43231
Description
A flaw was found in the media: radio-keene driver within the Linux kernel. This vulnerability occurs due to a memory leak in the usb_keene_probe() function's error path. If device registration fails, the video for Linux 2 (v4l2) control handler is not properly released, causing memory to be consumed over time. This can eventually lead to a Denial of Service (DoS) condition, making the system unstable or unresponsive.
