- wifi: mac80211: mlme: fix null-ptr deref on failed assoc
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: mlme: fix null-ptr deref on failed assoc
If association to an AP without a link 0 fails, then we crash in tracing because it assumes that either apmldaddr or link 0 BSS is valid, since we clear sdata->vif.validlinks and then don't add the apmld_addr to the struct.
Since we clear also sdata->vif.cfg.apaddr, keep a local copy of it and assign it earlier, before clearing validlinks, to fix this.
