CVE-2026-63919

The CVE-2026-63919 entry concerns the Linux kernel's xfrm input path and deferred transport reinjection. The vulnerability stems from storing a struct net pointer in skb->cb and later using it in xfrm_trans_reinject() without ensuring the netns lifetime, risking dereferencing a torn-down names...

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...

CVE-2026-63917

The CVE-2026-63917 entry describes a Linux kernel issue in vti6 where changing network namespaces (NETNS) after a tunnel is created can leave a stale netns reference, due to NETIF_F_NETNS_LOCAL being dropped from vti6 devices by commit 61220ab34948. This allows a vti6 tunnel to move across namesp...
