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.
