Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
Input: xpad - fix out-of-bounds access for Share button<br />
<br />
xpadone_process_packet() receives len directly from urb->actual_length<br />
and uses it to index the share-button byte at data[len - 18] or<br />
data[len - 26]. Since both len and data[0] are under the device&#39;s<br />
control, a broken controller can send a GIP_CMD_INPUT packet with<br />
actual_length
Impact
