Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> reset: gpio: suppress bind attributes in sysfs<br /> <br /> This is a special device that&amp;#39;s created dynamically and is supposed to<br /> stay in memory forever. We also currently don&amp;#39;t have a devlink between<br /> it and the actual reset consumer. Suppress sysfs bind attributes so that<br /> user-space can&amp;#39;t unbind the device because - as of now - it will cause a<br /> use-after-free splat from any user that puts the reset control handle.
