Description

HID: multitouch: Check to ensure report responses match the request

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.

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
