DescriptionIn the Linux kernel, the following vulnerability has been resolved: ieee802154: Avoid calling WARN_ON() on -ENOMEM in cfg802154_switch_netns() It's pointless to call WARN_ON() in case of an allocation failure in dev_change_net_namespace() and device_rename(), since it only leads to useless splats caused by deliberate fault injections, so avoid it. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
