[ Upstream commit 7d602f30149a117eea260208b1661bc404c21dfd ]
BUG: KFENCE: use-after-free read in __list_del_entry_valid+0x10/0xac
cdns3_wa2_remove_old_request()
{
...
kfree(priv_req->request.buf);
cdns3_gadget_ep_free_request(&priv_ep->endpoint, &priv_req->request);
list_del_init(&priv_req->list);
^^^ use after free
...
}
cdns3_gadget_ep_free_request() free the space pointed by priv_req,
but priv_req is used in the following list_del_init().
This patch move list_del_init() before cdns3_gadget_ep_free_request().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
