Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: phy: clean the sfp upstream if phy probing fails<br /> <br /> Sashiko reported that we don&amp;#39;t call sfp_bus_del_upstream() in the probe<br /> failure path, so let&amp;#39;s add it, otherwise the sfp-bus is left with a<br /> dangling &amp;#39;upstream&amp;#39; field, that may be used later on during SFP events.<br /> <br /> This issue existed before the generic phylib sfp support, back when<br /> drivers were calling phy_sfp_probe themselves.
