commit5d5f08fd0cupstream. A malicious user could pass an arbitrarily bad value to memdup_user_nul(), potentially causing kernel crash. This follows the same pattern as commitee76746387("netdevsim: prevent bad user input in nsim_dev_health_break_write()") Fixes:b6c7e873da("xtensa: ISS: add host file-based simulated disk") Fixes:16e5c1fc36("convert a bunch of open-coded instances of memdup_user_nul()") Cc: stable@vger.kernel.org Signed-off-by: Miaoqian Lin <linmq006@gmail.com> Message-Id: <20250829083015.1992751-1-linmq006@gmail.com> Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
