Description

A flaw was found in the Linux kernel's RDMA (Remote Direct Memory Access) ionic driver. This vulnerability occurs in the ionic_query_port() function, where a missing check for the return value of ib_device_get_netdev() can lead to a NULL pointer dereference. A local attacker could potentially exploit this to cause a system crash, resulting in a Denial of Service (DoS).
