Type: advisorySource: Official CVE List1 source record

In the Linux kernel, the following vulnerability has been resolved: bonding: fix xfrm real_dev null pointer dereference We shouldn't set real_dev to NULL because packets can be in transit and xfrm might call xdo_dev_offload_ok() in parallel. All callbacks assume real_dev is set.
