CVE-2026-43047
Description
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.
