  "details": "In the Linux kernel, the following vulnerability has been resolved:  wifi: mac80211: unlist vifs when their netdev is unregistered  mac80211 only removes vifs from the local-\u003einterfaces list when an interface is removed via ieee80211_if_remove(), before it unregisters the netdev. However, it's possible for a netdev to be unregistered without going through that: When the netns that holds the wiphy is destroyed, the wiphy is supposed to move to the init_ns, but that can run into allocation failures.  Then, mac80211 has an interface listed that doesn't exist, and will eventually hit    BUG: failure at net/wireless/core.h:141/wiphy_to_rdev()!   ...   _cfg80211_unregister_wdev+0x24/0x36a [cfg80211]   cfg80211_unregister_wdev+0x15/0x1d [cfg80211]   ieee80211_remove_interfaces+0x1ff/0x257 [mac80211]   ieee80211_unregister_hw+0x73/0x1d1 [mac80211]   mac80211_hwsim_del_radio+0x114/0x166 [mac80211_hwsim]  Remove the interface from the list in -\u003endo_uninit if it's still around to avoid this.",
