From 4958cf32f66df854b932b601eef2da3f95973339 Mon Sep 17 00:00:00 2001 From: Alexey Khoroshilov Date: Sun, 10 Aug 2014 23:35:11 +0700 Subject: usb: dbgp gadget: fix use after free in dbgp_unbind() After dbgp_bind()-dbgp_unbind() cycle happens, static variable dbgp contains pointers to already deallocated memory (dbgp.serial and dbgp.req). If the next dbgp_bind() fails, for example in usb_ep_alloc_request(), dbgp_bind() calls dbgp_unbind() on failure path, and dbgp_unbind() frees dbgp.serial that still stores a pointer to already deallocated memory. The patch sets pointers to NULL in dbgp_unbind(). Found by Linux Driver Verification project (linuxtesting.org).
