Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
HID: core: Mitigate potential OOB by removing bogus memset()<br />
<br />
The memset() in hid_report_raw_event() has the good intention of<br />
clearing out bogus data by zeroing the area from the end of the incoming<br />
data string to the assumed end of the buffer. However, as we have<br />
previously seen, doing so can easily result in OOB reads and writes in<br />
the subsequent thread of execution.<br />
<br />
The current suggestion from one of the HID maintainers is to remove the<br />
memset() and simply return if the incoming event buffer size is not<br />
large enough to fill the associated report.<br />
<br />
