CVE-2023-54025

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: rsi: Do not configure WoWlan in shutdown hook if not enabled<br /> <br /> In case WoWlan was never configured during the operation of the system,<br /> the hw-&gt;wiphy-&gt;wowlan_config will be NULL. rsi_config_wowlan() checks<br /> whether wowlan_config is non-NULL and if it is not, then WARNs about it.<br /> The warning is valid, as during normal operation the rsi_config_wowlan()<br /> should only ever be called with non-NULL wowlan_config. In shutdown this<br /> rsi_config_wowlan() should only ever be called if WoWlan was configured<br /> before by the user.<br /> <br /> Add checks for non-NULL wowlan_config into the shutdown hook. While at it,<br /> check whether the wiphy is also non-NULL before accessing wowlan_config .<br /> Drop the single-use wowlan_config variable, just inline it into function<br /> call.
