  1. CVE-2026-102623 6.5 Moyenne

    Red Hat OpenShift Virtualization 4

    A flaw was found in KubeVirt. An authenticated user with permission to create Virtual Machine Instances (VMIs) can cause a Denial of Service (DoS) by submitting a virtual machine definition with an empty ephemeral volume. The virt-controller component fails to properly validate the volume configuration, leading to an unhandled exception and application crash during processing. Because the malformed definition persists in the cluster, the controller enters a continuous crash loop, disrupting virtual machine lifecycle operations across the entire environment.

  2. CVE-2026-79705 4.5 Moyenne

    Red Hat Hardened Images · Red Hat Ansible Automation Platform 2 · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8

    A flaw was found in the buildah/copier Go package. When used outside of Buildah by a non-root caller, a crafted tar archive containing malicious symlinks can escape the target extraction directory and create files outside the intended destination. Buildah itself uses chroot hardening and is not affected.

  3. CVE-2026-79699 4.4 Moyenne

    Red Hat Ansible Automation Platform 2 · Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in the containers/storage library. A crafted tar archive containing a malicious whiteout header (e.g. victim/.wh.) can cause the extraction destination directory to be replaced with an arbitrary file when processed by storage/pkg/archive.UnpackLayer, ApplyLayer, or ApplyUncompressedLayer.
