CVE-2026-43138
概要

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.
