Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> igb: Initialize mailbox message for VF reset<br /> <br /> When a MAC address is not assigned to the VF, that portion of the message<br /> sent to the VF is not set. The memory, however, is allocated from the<br /> stack meaning that information may be leaked to the VM. Initialize the<br /> message buffer to 0 so that no information is passed to the VM in this<br /> case.
