Descriptions
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix potential key use-after-free
When ieee80211_key_link() is called by ieee80211_gtk_rekey_add()
but returns 0 due to KRACK protection (identical key reinstall),
ieee80211_gtk_rekey_add() will still return a pointer into the
key, in a potential use-after-free. This normally doesn't happen
since it's only called by iwlwifi in case of WoWLAN rekey offload
which has its own KRACK protection, but still better to fix, do
that by returning an error code and converting that to success on
the cfg80211 boundary only, leaving the error for bad callers of
ieee80211_gtk_rekey_add().
A use-after-free flaw was found in the Linux kernel’s IEEE 802.11 networking stack implementation functionality, used by Wifi, in how a user triggers the error path of the ieee80211_gtk_rekey_add function. This flaw allows a local user to crash the system.
