Описание
In the Linux kernel, the following vulnerability has been resolved:
media: i2c/tw9903: Fix potential memory leak in tw9903_probe()
In one of the error paths in tw9903_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.
A flaw was found in the tw9903 driver within the Linux kernel. This vulnerability occurs in an error handling path of the tw9903_probe() function, where memory allocated for video for Linux 2 (V4L2) control handlers is not properly released. This oversight can lead to a memory leak, potentially causing resource exhaustion and a Denial of Service (DoS) condition on the affected system.
