Vulnerability Title
bonding: fix xfrm real_dev null pointer dereference
Source: CVE Program / CVE List V5
Vulnerability Description
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.
