Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mailbox: add sanity check for channel array<br /> <br /> Fail gracefully if there is no channel array attached to the mailbox<br /> controller. Otherwise the later dereference will cause an OOPS which<br /> might not be seen because mailbox controllers might instantiate very<br /> early. Remove the comment explaining the obvious while here.
