However, its caller\nfs_any_create_table() will free ft->g again through calling\nmlx5e_destroy_flow_table(), which will lead to a double-free.\nFix this by setting ft->g to NULL in fs_any_create_groups().", "A double-free flaw was found in the Linux kernel ConnectX-4 and Connect-IB cards in the Mellanox driver. This issue could allow a local user to crash the system." ],
