commit 501e38a5531e ("usb: gadget: clear related members when goto fail")
Add two commits to all stable branches.
There are two bugs:
dev->buf does not need to be released if it already exists before
executing dev_config.
dev->config and dev->hs_config and dev->dev need to be cleaned if
dev_config fails to avoid UAF.
