  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: ibss: ref BSS entry for joined event\n\nWhen the IBSS is joined, we only record the BSSID/channel in the event\nand look up the BSS entry when processing it. However, that's racy,\ne.g. a new scan with NL80211_SCAN_FLAG_FLUSH can remove it, causing a\nwarning in the event work:\n\n  !bss\n  WARNING: net/wireless/ibss.c:37 at __cfg80211_ibss_joined+0x3d3/0x440\n  Workqueue: cfg80211 cfg80211_event_work\n   cfg80211_process_wdev_events+0x39f/0x5b0 net/wireless/util.c:1144\n   cfg80211_process_rdev_events+0xa1/0x110 net/wireless/util.c:1179\n   cfg80211_event_work+0x2f/0x40 net/wireless/core.c:393\n\nDo the lookup early (the driver is expected to only join an IBSS that\nhas a BSS entry) and keep a reference to it.",
