Description
An issue was discovered in the Linux kernel before 4.18.7. In create_qp_common in drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never initialized, resulting in a leak of stack memory to userspace.
A flaw was discovered in the Linux kernel's implementation of InfiniBand. A local attacker who is able to execute a read from the InfiniBand device could trigger an information leak of kernel memory to userspace which can be used to further attack the system.
