In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix potential NULL-ptr-dereference in_dev_get() can return NULL which will cause a failure once idev is dereferenced in in_dev_for_each_ifa_rtnl(). This patch adds a check for NULL value in idev beforehand. Found by Linux Verification Center (linuxtesting.org) with SVACE.
