CVE-2026-43138

reset: gpio: suppress bind attributes in sysfs

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.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
