NVD

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.
