Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: reject TDLS operations when station is not associated
syzbot triggered a WARN in ieee80211_tdls_oper() by sending
NL80211_TDLS_ENABLE_LINK immediately after NL80211_CMD_CONNECT,
before association completed and without prior TDLS setup.
This left internal state like sdata->u.mgd.tdls_peer uninitialized,
leading to a WARN_ON() in code paths that assumed it was valid.
Reject the operation early if not in station mode or not associated.
Affected configurations
• linux linux kernel (>= 3.17 < 6.1.148)
• linux linux kernel (>= 6.2 < 6.6.102)
• linux linux kernel (>= 6.7 < 6.12.42)
• linux linux kernel (>= 6.13 < 6.15.10)
• linux linux kernel (>= 6.16 < 6.16.1)
