Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-08 15:31

Details

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.

Severity ?

7.8 (High)
