A flaw was found in the Linux kernel's USB Video Class (UVC) gadget driver. This vulnerability occurs in the uvc_function_bind() and uvc_function_unbind() functions, where pointers to freed memory are not properly cleared. This can lead to a use-after-free (UAF) condition, potentially allowing an attacker to corrupt memory, which may result in a denial of service or arbitrary code execution.
