Description Dhananjay Arunesh 2019-11-21 11:04:25 UTC
A vulnerability was found in Linux Kernel where, a memory leak in the mlx5_fpga_conn_create_cq() function in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c allows attackers to cause a denial of service (memory consumption) by triggering mlx5_vector2eqn() failures.
