Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: usb: rtl8150: fix memory leak on usb_submit_urb() failure<br /> <br /> In async_set_registers(), when usb_submit_urb() fails, the allocated<br /> async_req structure and URB are not freed, causing a memory leak.<br /> <br /> The completion callback async_set_reg_cb() is responsible for freeing<br /> these allocations, but it is only called after the URB is successfully<br /> submitted and completes (successfully or with error). If submission<br /> fails, the callback never runs and the memory is leaked.<br /> <br /> Fix this by freeing both the URB and the request structure in the error<br /> path when usb_submit_urb() fails.
