A flaw was found in the Linux kernel's `tw9906` driver. An issue in an error path within the `tw9906_probe()` function can lead to a memory leak. Specifically, memory allocated during the initialization of the video for Linux 2 (V4L2) control handler is not properly released, which could result in system instability or resource exhaustion over time.

Upstream advisory: https://lore.kernel.org/linux-cve-announce/2026050601-CVE-2026-43246-ec1c@gregkh/T (In reply to OSIDB Bzimport from comment #0) > In the Linux kernel, the following vulnerability has been resolved: > > media: i2c/tw9906: Fix potential memory leak in tw9906_probe() > https://wackygame.org/ > In one of the error paths in tw9906_probe(), the memory allocated in > v4l2_ctrl_handler_init() and v4l2_ctrl_new_std() is not freed. Fix that > by calling v4l2_ctrl_handler_free() on the handler in that error path. This is one of those tiny-looking fixes that quietly improves long-term system stability. |
