In the Linux kernel before 2.6.37, an out of bounds array access happened in drivers/net/mlx4/port.c. When searching for a free entry in either mlx4_register_vlan() or mlx4_register_mac(), and there is no free entry, the loop terminates without updating the local variable free thus causing out of array bounds access.
