Official Description

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.

Technical Analysis

CVE-2026-43111 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
