Summary
cifs: fix underflow in parse_server_interfaces()
Details

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

cifs: fix underflow in parseserverinterfaces()

In this loop, we step through the buffer and after each item we check if the sizeleft is greater than the minimum size we need. However, the problem is that "bytesleft" is type ssizet while sizeof() is type sizet. That means that because of type promotion, the comparison is done as an unsigned and if we have negative bytes left the loop continues instead of ending.
