Call skb_shinfo() after gve_prep_tso() on DQO TX path.
gve_prep_tso() calls skb_cow_head(), which may reallocate
shinfo causing a use after free.
This bug was unintentionally fixed by 'a6fb8d5a8b69
("gve: Tx path for DQO-QPL")' while adding DQO-QPL format
support in 6.6. That patch is not appropriate for stable releases.
Fixes: a57e5de476 ("gve: DQO: Add TX path")

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.
