Date: Sun, 25 Jan 2015 10:07:49 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Mario Schuknecht <mario.schuknecht@...search-fe.de>, Felipe Balbi <balbi@...com> Subject: [PATCH 3.18 147/183] usb: gadget: gadgetfs: Free memory allocated by memdup_user() 3.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Mario Schuknecht <mario.schuknecht@...search-fe.de> commit b44be2462dbe3e23f0aedff64de52a1e8e47a1cd upstream. Commit 3b74c73f8d6f053f422e85fce955b61fb181cfe7 switched over to memdup_user() in ep_write() function and removed kfree (kbuf). memdup_user() function allocates memory which is never freed.
