Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: cfg80211: fix use-after-free in cmp_bss()

Following bss_free() quirk introduced in commit 776b3580178f ("cfg80211: track hidden SSID networks properly"), adjust cfg80211_update_known_bss() to free the last beacon frame elements only if they're not shared via the corresponding 'hidden_beacon_bss' pointer.
