CVE-2026-89734

CVE-2026-89734 is a null pointer dereference in the Linux kernel's USB gadget UVC driver. In the function uvcg_video_init(), if kthread_run_worker() fails, the error-handling path invokes uvcg_err(), which dereferences video->uvc. However, at that point in initialization the pointer has not ye...
