Subject: [PATCH 2/4] HID: corsair-void: fix out-of-bounds read in corsair_void_raw_event
Date: Tue, 14 Jul 2026 21:16:09 +0800 [thread overview]

In-Reply-To: <20260714131611.269929-1-yaojiale02@163.com>
Both the STATUS_REPORT and FIRMWARE_REPORT paths access data[4].
Add a size < 5 guard before the report dispatch.
