In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: don't trust firmware n_channels
If the firmware sends us a corrupted MCC response with
n_channels much larger than the command response can be,
we might copy far too much (uninitialized) memory and
even crash if the n_channels is large enough to make it
run out of the one page allocated for the FW response.
Fix that by checking the lengths. Doing a < comparison
would be sufficient, but the firmware should be doing
it correctly, so check more strictly.
