  "title": "wifi: cfg80211: ibss: ref BSS entry for joined event",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  wifi: cfg80211: ibss: ref BSS entry for joined event  When the IBSS is joined, we only record the BSSID/channel in the event and look up the BSS entry when processing it. However, that\u0027s racy, e.g. a new scan with NL80211_SCAN_FLAG_FLUSH can remove it, causing a warning in the event work:    !bss   WARNING: net/wireless/ibss.c:37 at __cfg80211_ibss_joined\u002B0x3d3/0x440   Workqueue: cfg80211 cfg80211_event_work    cfg80211_process_wdev_events\u002B0x39f/0x5b0 net/wireless/util.c:1144    cfg80211_process_rdev_events\u002B0xa1/0x110 net/wireless/util.c:1179    cfg80211_event_work\u002B0x2f/0x40 net/wireless/core.c:393  Do the lookup early (the driver is expected to only join an IBSS that has a BSS entry) and keep a reference to it.",
