In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
wifi: mac80211: don’t start a ROC while scanning<\/p>\n
The ROC work can be pending when a scan starts (which requires
\nROC list to be empty, but that’s possible), and then a new ROC
\ncan be added to the list and the work will pick it up.<\/p>\n
Avoid starting that ROC if a scan made it between things, as
\notherwise we’ll hit a warning later:<\/p>\n
