CVE-2026-43111

A flaw was found in the Linux kernel's roccat Human Interface Device (HID) driver. This vulnerability, a use-after-free, arises from a synchronization issue where the roccat_report_event() function accesses a list of readers without adequate locking. A local attacker could exploit this to cause a system crash (denial of service) or potentially execute arbitrary code, compromising system integrity.

Red Hat acknowledges the upstream Linux kernel correction for «HID» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the hid_roccat module from being loaded. See https://access.redhat.com/solutions/41278 for instructions.
