CVE-2026-43111

In the Linux kernel, the following vulnerability has been resolved:

HID: roccat: fix use-after-free in roccat_report_event

roccat_report_event() iterates over the device->readers list without
holding the readers_lock. This allows a concurrent roccat_release() to
remove and free a reader while it’s still being accessed, leading to a
use-after-free.

Protect the readers list traversal with the readers_lock mutex.
