CVE-2026-74310

In the Linux kernel, the following vulnerability has been resolved: vhost/net: complete zerocopy ubufs only once vhost-net initializes one ubufinfo per outstanding zerocopy TX descriptor and hands it to the backend socket. The networking stack may then clone a zerocopy skb before all skb referenc...

CVE-2026-74286

In the Linux kernel, the following vulnerability has been resolved: net: pfcp: allocate per-cpu tstats for PFCP netdevs PFCP uses devgettstats64 as its ndogetstats64 callback, but pfcplinksetup does not request NETDEVPCPUSTATTSTATS. The net core therefore leaves dev-tstats NULL for PFCP devices...
