[ Upstream commit a10feaf8c464c3f9cfdd3a8a7ce17e1c0d498da1 ] The function at issue does not always initialize each byte allocated for 'b' and can therefore leak uninitialized memory to a USB device in the call to usb_bulk_msg() Use kzalloc() instead of kmalloc() Signed-off-by: Tomas Bortoli <tomasbortoli@gmail.com> Reported-by: syzbot+0522702e9d67142379f1@syzkaller.appspotmail.com Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
