In the Linux kernel, the following vulnerability has been resolved: reset: gpio: suppress bind attributes in sysfs This is a special device that's created dynamically and is supposed to stay in memory forever. We also currently don't have a devlink between it and the actual reset consumer. Suppress sysfs bind attributes so that user-space can't unbind the device because - as of now - it will cause a use-after-free splat from any user that puts the reset control handle.
