Revision 218854af84038d828a32f061858b1902ed2beec6 authored by Dan Rosenberg on 17 November 2010, 06:37:16 UTC, committed by David S. Miller on 17 November 2010, 20:20:52 UTC
In rds_cmsg_rdma_args(), the user-provided args->nr_local value is restricted to less than UINT_MAX. This seems to need a tighter upper bound, since the calculation of total iov_size can overflow, resulting in a small sock_kmalloc() allocation. This would probably just result in walking off the heap and crashing when calling rds_rdma_pages() with a high count value. If it somehow doesn't crash here, then memory corruption could occur soon after. Signed-off-by: Dan Rosenberg <drosenberg@vsecurity.com> Signed-off-by: David S. Miller <davem@davemloft.net>
