Description

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: Fix use after free for wext Key information in wext.connect is not reset on (re)connect and can hold data from a previous connection. Reset key data to avoid that drivers or mac80211 incorrectly detect a WEP connection request and access the freed or already reused memory. Additionally optimize cfg80211_sme_connect() and avoid an useless schedule of conn_work.

Affected configurations

• linux linux kernel (>= 2.6.32 < 4.14.308) • linux linux kernel (>= 4.15 < 4.19.276) • linux linux kernel (>= 4.20 < 5.4.235) • linux linux kernel (>= 5.5 < 5.10.173) • linux linux kernel (>= 5.11 < 5.15.99) • linux linux kernel (>= 5.16 < 6.1.16) • linux linux kernel (>= 6.2 < 6.2.3)
