Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
HID: multitouch: Check to ensure report responses match the request<br />
<br />
It is possible for a malicious (or clumsy) device to respond to a<br />
specific report&#39;s feature request using a completely different report<br />
ID. This can cause confusion in the HID core resulting in nasty<br />
side-effects such as OOB writes.<br />
<br />
Add a check to ensure that the report ID in the response, matches the<br />
one that was requested. If it doesn&#39;t, omit reporting the raw event and<br />
return early.
