CVE-2026-63919

In the Linux kernel, the following vulnerability has been resolved: xfrm: input: hold netns during deferred transport reinjection Transport-mode reinjection stores a struct net pointer in skb-cb and uses it later from xfrmtransreinject. That pointer must stay valid until the deferred callback run...
