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. (NVD)
