Dan Carpenter dbdfefc71a virtio_ring: Fix two use after free bugs [ Upstream commit `e152d8af42` ] The "vq" struct is added to the "vdev->vqs" list prematurely. If we encounter an error later in the function then the "vq" is freed, but since it is still on the list that could lead to a use after free bug. Fixes: `cbeedb72b9` ("virtio_ring: allocate desc state for split ring separately") Reported-by: Robert Buhren <robert.buhren@sect.tu-berlin.de> Reported-by: Felicitas Hetzelt <file@sect.tu-berlin.de> Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Link: https://lore.kernel.org/r/X8pGaG/zkI3jk8mk@mwanda Signed-off-by: Michael S.

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.
