CVE-2010-4656: Buffer Overflow

Published Jan 25, 2011
·
Updated

If the iowarrior devices in this case statement support more than 8 bytes per report, it is possible to write past the end of a kernel heap allocation. This will probably never be possible, but change the allocation to be more defensive anyway.
