This leads to not disconnecting, which we should. For Intel devices, this can lead to a firmware crash.</p> <p>Fix this by using an int type for the channel number as well as the opclass, and using a (negative) value that cannot be encoded in the element to indicate it&#39;s not present.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>wifi: mac80211: disconnect on CSA to channel 0</p> <p>The refactor for the CSA parsing erroneously equates channel zero and no information present, leading it to ignore a CSA on an AP that advertises a switch to that (invalid) channel.
