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.","affected":[{"package":{"name":"kubevirt.io/kubevirt","ecosystem":"Go","purl":"pkg:golang/kubevirt.io/kubevirt"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.8.0-alpha.0"},{"fixed":"1.8.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-7jcp-v9w4-wjmg/GHSA-7jcp-v9w4-wjmg.json"}},{"package":{"name":"kubevirt.io/kubevirt","ecosystem":"Go","purl":"pkg:golang/kubevirt.io/kubevirt"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.7.0-alpha.0"},{"fixed":"1.7.4"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-7jcp-v9w4-wjmg/GHSA-7jcp-v9w4-wjmg.json"}},{"package":{"name":"kubevirt.io/kubevirt","ecosystem":"Go","purl":"pkg:golang/kubevirt.io/kubevirt"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.6.6"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-7jcp-v9w4-wjmg/GHSA-7jcp-v9w4-wjmg.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7374"},{"type":"WEB","url":"https://github.com/kubevirt/kubevirt/pull/17916"},{"type":"WEB","url":"https://github.com/kubevirt/kubevirt/commit/011eef8129e2c21e0ea496f283ee1676009bc757"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-7374.json"},{"type":"PACKAGE","url":"https://github.com/kubevirt/kubevirt"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2463728"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-7374"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20975"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20890"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20886"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20866"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20825"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20782"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20767"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20763"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20736"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:20720"}],"database_specific":{"cwe_ids":["CWE-59"],"github_reviewed":true,"github_reviewed_at":"2026-06-30T18:04:03Z","nvd_published_at":"2026-05-26T14:16:40Z","severity":"CRITICAL"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
