Details

In the Linux kernel, the following vulnerability has been resolved:

drm/vmwgfx: Fix stale file descriptors on failed usercopy

A failing usercopy of the fencerep object will lead to a stale entry in the file descriptor table as putunused_fd() won't release it. This enables userland to refer to a dangling 'file' object through that still valid file descriptor, leading to all kinds of use-after-free exploitation scenarios.

Fix this by deferring the call to fd_install() until after the usercopy has succeeded.
