CVE-2026-13218

CVE-2026-13218 : In KubeVirt, the virt-handler network cache handling allows a symlink attack via WriteToCachedFile, which writes to a launcher-rooted path with os.WriteFile and os.Chown. A user inside the virt-launcher container can place a symlink at the cache path, causing virt-handler to foll...

CVE-2026-13325

The CVE-2026-13325 issue affects KubeVirt’s migration proxy. When spec.configuration.migrations.disableTLS is set to true, the target virt-handler binds a plain TCP listener on all interfaces (0.0.0.0/::) on a random port with no authentication, peer allow-list, or handshake token. This listener ...

CVE-2026-13318

KubeVirt exposes an SSRF in virt-api port-forward: when handling a port-forward to a VirtualMachineInstance, virt-api reads vmi.Status.Interfaces[0].IP and dials it without validation. For VMIs using non-masquerade networks (bridge or secondary-only), this IP is supplied by the in-guest QEMU agen...

CVE-2026-13322

CVE-2026-13322 affects KubeVirt, specifically the virt-handler on RHEL9, where the downward metrics virtio-serial server uses textproto.Reader.ReadLine() to read guest requests. The read is unbounded: there is no maximum length or read deadline, so a user with access to a VM guest can send an ong...

CVE-2026-13434

CVE-2026-13434 affects KubeVirt’s network annotation generator used when provisioning VirtualMachineInstance with Multus networks. The flaw writes the supplied networkName verbatim into the v1.multus-cni.io/default-network annotation without format validation or sanitization, with only an empty-s...

CVE-2026-13208

CVE-2026-13208 describes a flaw in KubeVirt where virt-handler’s domain notify server trusts VMI identity from the unvalidated request body. The gRPC handlers for HandleDomainEvent and HandleK8SEvent derive the VMI (namespace/name) solely from the request payload, with no identity validation agai...

CVE-2026-13201

CVE-2026-13201 concerns KubeVirt’s safepath package, where OpenAtNoFollow uses O_PATH|O_NOFOLLOW to obtain a descriptor for a path leaf, but downstream helpers access paths via /proc/self/fd/N. If the leaf is a symlink, the kernel dereferences it, bypassing intended no-follow protection. An attac...
