Revision 21643e69a4c06f7ef155fbc70e3fba13fba4a756 authored by Dan Carpenter on 04 November 2011, 18:24:08 UTC, committed by Konrad Rzeszutek Wilk on 16 November 2011, 17:13:47 UTC
On 32 bit systems a high value of op.count could lead to an integer overflow in the kzalloc() and gref_ids would be smaller than expected. If the you triggered another integer overflow in "if (gref_size + op.count > limit)" then you'd probably get memory corruption inside add_grefs().
