CVE-2026-89629: HID: corsair-void: Check size of status and firmware events before reading them

[Greg Kroah-Hartman]

From: Greg Kroah-Hartman <gregkh@kernel.org>

Description
===========

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.

The Linux kernel CVE team has assigned CVE-2026-89629 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
