Description Dhananjay Arunesh 2019-08-20 09:55:28 UTC 
A vulnerability was found in the Linux kernel, 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.

Adding VLAN or MAC addresses are administrative actions or require CAP_NET_ADMIN capabilities to execute these instructions, regular local users can not trigger this flaw.
