CVE-2022-50533

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: mac80211: mlme: fix null-ptr deref on failed assoc<br /> <br /> If association to an AP without a link 0 fails, then we crash in<br /> tracing because it assumes that either ap_mld_addr or link 0 BSS<br /> is valid, since we clear sdata-&gt;vif.valid_links and then don&amp;#39;t<br /> add the ap_mld_addr to the struct.<br /> <br /> Since we clear also sdata-&gt;vif.cfg.ap_addr, keep a local copy of<br /> it and assign it earlier, before clearing valid_links, to fix<br /> this.
