CVE-2026-13318

A server-side request forgery SSRF flaw was found in KubeVirt's virt-api port-forward handler. When processing a port-forward request to a VirtualMachineInstance VMI, virt-api reads the target IP from vmi.Status.Interfaces0.IP and passes it directly to net.Dial without validation. For VMIs using...

CVE-2026-53221

The CVE-2026-53221 issue affects the Linux kernel’s IPsec/tunnel implementation, specifically ip6_vti in vti6_tnl_lookup. The vulnerability arises when an exact tunnel match fails and a fallback search for wildcard tunnels is performed; tunnels of different types are stored together in a single h...

EUVD-2026-39312

In the Linux kernel, the following vulnerability has been resolved: ip6vti: fix incorrect tunnel matching in vti6tnllookup In vti6tnllookup, when an exact match for a tunnel fails, the code falls back to searching for wildcard tunnels: - Tunnels matching the packet's local address, with any remot...

CVE-2026-53070

CVE-2026-53070 affects the Linux kernel SCTP over UDP. The issue arises because bh (bottom half) handling must stay disabled when calling udp_tunnel_xmit_skb()/udp_tunnel6_xmit_skb(); after the 6f1a9140 patch, the context can move between CPUs, breaking dev_xmit_recursion_inc()/dec() balance and ...

EUVD-2026-38710

In the Linux kernel, the following vulnerability has been resolved: tun: zero the whole vnet header in tunputuser tunputuser declares an on-stack struct virtionethdrv1hashtunnel without zeroing it. For a non-tunnel skb, virtionethdrtnlfromskb only initializes the first 10 bytes sizeofstruct...

CVE-2026-52940

CVE-2026-52940 affects the Linux kernel tun module. In tun_put_user(), an on-stack struct virtio_net_hdr_v1_hash_tunnel is declared but not zeroed; for non-tunnel skbs, virtio_net_hdr_tnl_from_skb() initializes only the first 10 bytes of the 24-byte header, leaving bytes 10–23 as stack garbage. I...

kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()

A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash denial of...
