Subject: [patch] PM / hibernate: memory corruption in resumedelay_setup()
Date: Wed, 14 May 2014 12:57:20 +0000 [thread overview]
Message-ID: <20140514125720.GC14571@mwanda> (raw)
"resume_delay" is not an unsigned long, it's an int, so this will
corrupt memory on 64 bit systems.
Fixes: 317cf7e5e85e ('PM / hibernate: convert simple_strtoul to kstrtoul')
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
