CVE-2019-19045 is a medium-severity vulnerability rated 4.4/10 on the CVSS scale. A memory leak in the mlx5_fpga_conn_create_cq() function in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering mlx5_vector2eqn() failures, aka CID-c8c2a057fdc7.. EPSS estimates a 0.56% chance of exploitation in the next 30 days.
