In the Linux kernel, the following vulnerability has been resolved:

HID: core: Mitigate potential OOB by removing bogus memset()

The memset() in hid_report_raw_event() has the good intention of

clearing out bogus data by zeroing the area from the end of the incoming

data string to the assumed end of the buffer. However, as we have

previously seen, doing so can easily result in OOB reads and writes in

the subsequent thread of execution.

The current suggestion from one of the HID maintainers is to remove the

memset() and simply return if the incoming event buffer size is not

large enough to fill the associated report.
