Описание
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.
An out-of-bounds read flaw was found in the mix4 Linux kernel driver. Registering the last of a VLAN or MAC address with no free entries may cause an out-of-bounds read into the next page of memory, causing a panic if the page is not available. The command can only be executed by a local privileged user with CAP_NET_ADMIN or CAP_SYS_ADMIN capabilities. The largest threat from this vulnerabilty is availability to the system.
