Description OSIDB Bzimport 2026-08-28 07:45:39 UTC 
In 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.
