In the Linux kernel, the following vulnerability has been resolved:
mm: gup: stop abusing try_grab_folio
A kernel warning was reported when pinning folio in CMA memory when
launching SEV virtual machine. The splat looks like:
[ 464.325306] WARNING: CPU: 13 PID: 6734 at mm/gup.c:1313 __get_user_pages+0x423/0x520

Per the analysis done by yangge, when starting the SEV virtual machine, it
will call pin_user_pages_fast(..., FOLL_LONGTERM, ...) to pin the memory.
But the page is in CMA area, so fast GUP will fail then fallback to the
slow path due to the longterm pinnalbe check in try_grab_folio().
The slow path will try to pin the pages then migrate them out of CMA area.
But the slow path also uses try_grab_folio() to pin the page, it will
also fail due to the same check then the above warning is triggered.
In addition, the try_grab_folio() is supposed to be used in fast path and
it elevates folio refcount by using add ref unless zero. We are guaranteed
to have at least one stable reference in slow path, so the simple atomic add
could be used. The performance difference should be trivial, but the
misuse may be confusing and misleading.
Redefined try_grab_folio() to try_grab_folio_fast(), and try_grab_page()
to try_grab_folio(), and use them in the proper paths. This solves both
the abuse and the kernel warning.
The proper naming makes their usecase more clear and should prevent from
abusing in the future.

The Funnelforms Free plugin for WordPress is vulnerable to arbitrary file deletion in all versions up to, and including, 3.7.3.2 via the 'af2DeleteFontFile' function. This is due to the plugin not properly validating a file or its path prior to deleting it. This makes it possible for unauthenticated attackers to delete arbitrary files, including the wp-config.php file, which can make site takeover and remote code execution possible.

The Funnelforms Free plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'af2_add_font' function in all versions up to, and including, 3.7.3.2. This makes it possible for authenticated attackers, with administrator-level and above permissions, to upload arbitrary files on the affected site's server which may make remote code execution possible.
