In the Linux kernel, the following vulnerability has been resolved:
ieee802154: Avoid calling WARNON() on -ENOMEM in cfg802154switch_netns()
It's pointless to call WARNON() in case of an allocation failure in devchangenetnamespace() and device_rename(), since it only leads to useless splats caused by deliberate fault injections, so avoid it.
