CVE-2023-52530

  3. CVE-2023-52530
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().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: mac80211: soluciona el posible Use After Free de la clave Cuando ieee80211_key_link() es llamado por ieee80211_gtk_rekey_add() pero devuelve 0 debido a la protección KRACK (reinstalación de clave idéntica), ieee80211_gtk_rekey_add() aún devolverá un puntero a la clave, en un posible Use After Free. Esto normalmente no sucede ya que iwlwifi solo lo llama en caso de descarga de recodificación de WoWLAN, que tiene su propia protección KRACK, pero aún es mejor solucionarlo, hágalo devolviendo un código de error y convirtiéndolo en exitoso solo en el límite cfg80211, dejando el error para personas que llaman mal de ieee80211_gtk_rekey_add().
