Summary

In the Linux kernel, the following vulnerability has been resolved:

net: txgbe: leave space for null terminators on property_entry

Lists of struct property_entry are supposed to be terminated with an empty property, this driver currently seems to be allocating exactly the amount of entry used.

Change the struct definition to leave an extra element for all property_entry.
