Title
ethtool: Fix uninitialized number of lanes
Summary
In the Linux kernel, the following vulnerability has been resolved: ethtool: Fix uninitialized number of lanes It is not possible to set the number of lanes when setting link modes using the legacy IOCTL ethtool interface. Since 'struct ethtool_link_ksettings' is not initialized in this path, drivers receive an uninitialized number of lanes in 'struct ethtool_link_ksettings::lanes'. When this information is later queried from drivers, it results in the ethtool code making decisions based on uninitialized memory, leading to the following KMSAN splat [1]. In practice, this most likely only happens with the tun driver that simply returns whatever it got in the set operation. As far as I can tell, this uninitialized memory is not leaked to user space thanks to the 'ethtool_ops->cap_link_lanes_supported' check in linkmodes_prepare_data(). Fix by initializing the structure in the IOCTL path. Did not find any more call sites that pass an uninitialized structure when calling 'ethtool_ops::set_link_ksettings()'.

Since \u0027struct\\nethtool_link_ksettings\u0027 is not initialized in this path, drivers receive\\nan uninitialized number of lanes in \u0027struct\\nethtool_link_ksettings::lanes\u0027.\\n\\nWhen this information is later queried from drivers, it results in the\\nethtool code making decisions based on uninitialized memory, leading to\\nthe following KMSAN splat [1]. In practice, this most likely only\\nhappens with the tun driver that simply returns whatever it got in the\\nset operation.\\n\\nAs far as I can tell, this uninitialized memory is not leaked to user\\nspace thanks to the \u0027ethtool_ops-\u003ecap_link_lanes_supported\u0027 check in\\nlinkmodes_prepare_data().\\n\\nFix by initializing the structure in the IOCTL path.
