{"id":"CVE-2026-7374","aliases":["GHSA-7jcp-v9w4-wjmg","GO-2026-5848"],"url":"https://o3.security/vulnerability/CVE-2026-7374","summary":"Kubevirt: kubevirt virt-handler: privilege escalation and node compromise via symlink following vulnerability","details":"A flaw was found in KubeVirt's virt-handler component. This vulnerability allows an authenticated OpenShift user with edit permissions in a single namespace to exploit improper symlink validation when connecting to virtual machine console sockets. By replacing the console socket with a symlink to the host's container runtime (CRI-O) socket, an attacker can hijack virt-handler's privileged connection. This enables the attacker to access any Unix socket on the host, potentially leading to full control of the node and the entire cluster.","published":"2026-05-26T13:14:53.851Z","modified":"2026-09-12T03:30:29.352337232Z","cvss":{"score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":{"score":0.00742,"percentile":0.51898,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"kubevirt.io/kubevirt","fixedVersion":"1.8.3"},{"ecosystem":"Go","name":"kubevirt.io/kubevirt","fixedVersion":"1.7.4"},{"ecosystem":"Go","name":"kubevirt.io/kubevirt","fixedVersion":"1.6.6"}],"fix":{"url":"https://github.com/kubevirt/kubevirt/pull/17916","label":"kubevirt/kubevirt#17916"},"references":[{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-7374.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20720"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20736"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20763"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20767"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20782"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20825"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20866"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20886"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20890"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20975"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-7374"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/7xxx/CVE-2026-7374.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7374"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2463728"},{"type":"PACKAGE","url":"https://github.com/kubevirt/kubevirt"},{"type":"WEB","url":"https://github.com/kubevirt/kubevirt/pull/17916"},{"type":"WEB","url":"https://github.com/kubevirt/kubevirt/commit/011eef8129e2c21e0ea496f283ee1676009bc757"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-12T03:30:29.352337232Z"}}
