From d5ce5b40bc66880d1732461d4b47d7fc3331ed30 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Wed, 8 Jul 2009 11:17:34 +0100 Subject: [PATCH] Free the memory allocated by memdup_user() in fs/sysfs/bin.c Commit 1c8542c7bb replaced kmalloc() with memdup_user() in the write() function but also dropped the kfree(temp). The memdup_user() function allocates memory which is never freed.
