    Описание

    Оригинално описание

    In the Linux kernel, the following vulnerability has been resolved: media: video-i2c: fix kthread error pointer left in kthread_vid_cap on failure kthread_run() returns an ERR_PTR on failure, not NULL. When start_streaming() fails, data->kthread_vid_cap is left holding this error pointer instead of being cleared. This causes two subsequent bugs: 1. A future call to start_streaming() sees a non-NULL kthread_vid_cap and returns 0 (success) immediately, without actually starting the capture thread. 2. A call to stop_streaming() checks 'kthread_vid_cap == NULL' which is false for an error pointer, and proceeds to call kthread_stop() on the error pointer, leading to a kernel crash. Fix this by resetting kthread_vid_cap to NULL on failure before jumping to the error path.
