CVE-2026-98337
wifi: mac80211: don't start a ROC while scanning
Description
In 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: WARNING: net/mac80211/offchannel.c:404 at ieee80211_start_next_roc+0x256/0x2d0 Workqueue: events_unbound cfg80211_wiphy_work Call Trace: __ieee80211_scan_completed+0x4fd/0xe40 net/mac80211/scan.c:537 ieee80211_scan_work+0x472/0x1ff0 net/mac80211/scan.c:1193 cfg80211_wiphy_work+0x410/0x570 net/wireless/core.c:513
