CVE-2026-43047 POC (Proof-of-Concept)

In the Linux kernel, the following vulnerability has been resolved:
HID: multitouch: Check to ensure report responses match the request
It is possible for a malicious (or clumsy) device to respond to a
specific report's feature request using a completely different report
ID. This can cause confusion in the HID core resulting in nasty
side-effects such as OOB writes.
Add a check to ensure that the report ID in the response, matches the
one that was requested. If it doesn't, omit reporting the raw event and
return early.
