CVE-2026-98337In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't start a ROC while scanning
The ROC work can be pending when a scan starts (which requires
ROC list to be empty, but that's possible), and then a new ROC
can be added to the list and the work will pick it up.
Avoid starting that ROC if a scan made it between things, as
otherwise we'll hit a warning later:
