Описание

In the Linux kernel, the following vulnerability has been resolved: RDMA/ionic: Fix potential NULL pointer dereference in ionic_query_port The function ionic_query_port() calls ib_device_get_netdev() without checking the return value which could lead to NULL pointer dereference, Fix it by checking the return value and return -ENODEV if the 'ndev' is NULL.

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).
