Vulnerability from github – Published: 2026-08-28 09:31 – Updated: 2026-08-28 09:31

Details

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.
