New Zapscape KVM Flaw Could Let Privileged L1 Guest Code Escape to Linux Hosts

Zapscape , a new Linux kernel vulnerability, could allow an attacker with kernel privileges inside an L1 guest virtual machine VM to escape KVM isolation and execute code on the host. The risk applies when nested virtualization is exposed to untrusted guests. The flaw is tracked as CVE-2026-64561...

CVE-2026-64562

CVE-2026-64562 : In the Linux kernel KVM nVMX, a shadow VMCS could be freed prematurely by free_nested() while vmcs01 still referenced it. Since this occurs asynchronously with respect to loaded_vmcs_clear(), a vCPU could migrate and __loaded_vmcs_clear() may then execute VMCLEAR. The vulnerabili...
