Description

In the Linux kernel, the following vulnerability has been resolved:

ethtool: module: avoid leaking a netdev ref on module flash errors

module_flash_fw_schedule() is missing undo for setting the "in_progress" flag and taking the netdev reference. Delay taking these, the device can't disappear while we are holding rtnl_lock.
