CVE-2026-89629: HID: corsair-void: Check size of status and firmware events before reading them
In the Linux kernel, the following vulnerability has been resolved:
HID: corsair-void: Check size of status and firmware events before reading them
Malformed status and firmware events could cause an out-of-bounds read since the size wasn't being checked. Check the size and warn on unexpected values to avoid this.

Frequently Asked Questions
Which systems are relevant to this issue?
Systems using the Linux kernel's corsair-void HID driver are relevant. The provided information does not identify affected kernel versions or whether the driver is enabled by default.
What would an attacker need to do to trigger the flaw?
An attacker would need to cause the driver to process malformed status or firmware events with unexpected sizes. Before the fix, those events could lead to an out-of-bounds read.
