{"id":"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.","aliases":["GHSA-7jcp-v9w4-wjmg","GO-2026-5848"],"modified":"2026-09-12T03:30:29.352337232Z","published":"2026-05-26T13:14:53.851Z","related":["SUSE-SU-2026:2077-1","SUSE-SU-2026:2400-1","SUSE-SU-2026:2401-1","openSUSE-SU-2026:21483-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/7xxx/CVE-2026-7374.json","cna_assigner":"redhat","cwe_ids":["CWE-59"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kubevirt/kubevirt","events":[{"introduced":"0"},{"fixed":"75581da2192a3c4f9e0c48e7e37255ed2257780d"},{"introduced":"50b9b4d0cf1caaf56147411a1e6765134e0e82b9"},{"fixed":"2468b19f25de2991433ba44e45419b2c0eaec20a"},{"introduced":"85b6a25964132b0d578184598fb3c00d00d71f61"},{"fixed":"540f37cfa3caed601ac6710cb002b11a249d0639"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.6.6"},{"introduced":"1.7.0"},{"fixed":"1.7.4"},{"introduced":"1.8.0"},{"fixed":"1.8.3"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.6.5","v1.7.3","v1.8.2","v1.8.1","v1.8.0-rc.1","v1.8.0","v1.7.2","v1.6.4","v1.7.1","v1.7.0-rc.1","v1.7.0","v1.6.3","v1.6.2","v1.6.1","v1.6.0-rc.1","v1.6.0","v1.6.0-rc.0","v1.6.0-beta.0","v1.6.0-alpha.0","v1.5.0-beta.0","v1.5.0-alpha.0","v1.4.0-rc.0","v1.4.0-alpha.1","v1.4.0-alpha.0","v1.3.0-beta.0","v1.3.0-alpha.0","v1.2.0-rc.0","v1.2.0-beta.0","v1.2.0-alpha.0","v1.1.0-rc.0","v1.1.0-alpha.0","v1.0.0-beta.0","v1.0.0-alpha.0","v0.60.0-alpha.0","v0.59.0-rc.1","v0.59.0-rc.0","v0.59.0-alpha.2","v0.59.0-alpha.1","v0.59.0-alpha.0","v0.58.0-rc.0","v0.58.0","v0.57.0-rc.0","v0.57.0","v0.56.0-rc.0","v0.55.0-rc.0","v0.55.0","v0.54.0-rc.0","v0.54.0","v0.53.0-rc.0","v0.53.0","v0.52.0-rc.0","v0.52.0","v0.51.0-rc.0","v0.51.0","v0.50.0-rc.0","v0.50.0","v0.49.0-rc.0","v0.49.0","v0.48.0-rc.0","v0.48.0","v0.47.0-rc.0","v0.46.0-rc.0","v0.46.0","v0.45.0-rc.0","v0.45.0","v0.44.0-rc.0","v0.44.0","v0.43.1-rc.1","v0.43.0-rc.0","v0.35.0-rc.0","v0.35.0","v0.42.0-rc.0","v0.42.0","v0.41.0-rc.0","v0.40.0-rc.0","v0.39.0-rc.0","v0.38.0-rc.0","v0.38.0","v0.37.0-rc.0","v0.36.0-rc.0","v0.34.0-rc.0","v0.33.0-rc.0","v0.32.0-rc.1","v0.31.0-rc.1","v0.31.0","v0.30.0-rc.4","v0.30.0","v0.30.0-rc.2","v0.30.0-rc.3","v0.30.0-rc.0","v0.30.0-rc.1","v0.29.0-rc.1","v0.29.0","v0.29.0-rc.0","v0.28.0-rc.2","v0.28.0-rc.0","v0.28.0-rc.1","v0.28.0","v0.27.0-rc.0","v0.27.0","v0.26.1","v0.26.0-rc.0","v0.26.0","v0.25.0-rc.0","v0.25.0","v0.24.0","v0.23.0","v0.22.0","v0.21.0","v0.20.0","v0.19.0-rc.0","v0.19.0","v0.18.0","v0.17.0","v0.17.0-alpha.1","v0.17.0-alpha.0","v0.16.0","v0.16.0-alpha.0","v0.15.0","v0.15.0-alpha.0","v0.14.0","v0.13.0","v0.12.0","v0.12.0-alpha.3","v0.12.0-alpha.2","v0.12.0-alpha.1","v0.11.1","v0.10.0","v0.11.0","v0.12.0-alpha.0","v0.9.3","v0.9.2","v0.9.1","v0.9.0","v0.9.0-alpha.1","v0.8.0","v0.9.0-alpha.0","v0.8.0-alpha.2","v0.8.0-alpha.1","v0.8.0-alpha.0","v0.7.0","v0.7.0-alpha.2","v0.6.1","v0.7.0-alpha.5","v0.7.0-alpha.4","v0.7.0-alpha.3","v0.7.0-alpha.1","v0.7.0-alpha.0","v0.6.1-alpha.0","v0.6.0","v0.5.1-alpha.3","v0.5.1-alpha.2","v0.5.1-alpha.1","v0.5.0","v0.5.0-alpha.1","v0.5.0-alpha.0","v0.4.1","v0.4.1-alpha.2","v0.4.1-alpha.1","v0.4.0","v0.4.0-alpha.2","v0.4.0-alpha.1","v0.4.0-alpha.0","v0.3.0","v0.3.0-alpha.4","v0.3.0-alpha.0","v0.3.0-alpha.3","v0.3.0-alpha.2","v0.3.0-alpha.1","v0.2.0","v0.1.0","v0.1.0-alpha","v0.0.4","v0.0.3","v0.0.2","v0.0.1-alpha.6","v0.0.1-alpha.5","v0.0.1-alpha.4","v0.0.1-alpha.3","v0.0.1-alpha.2","v0.0.1-alpha.1","v0.0.1-alpha.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-7374.json"}}],"schema_version":"1.9.0","severity":[{"t
