The OpenAtNoFollow function uses O_PATH|O_NOFOLLOW to obtain a file descriptor to a path leaf, but downstream operations resolve the path via /proc/self/fd/N using link-following syscalls. When the leaf is a symlink, the kernel dereferences it, defeating the intended no-follow protection. An attacker with access to a virt-launcher pod can exploit this to redirect virt-handler's IPC socket connections, including the notify socket used for VM domain lifecycle events. By hijacking this socket, the attacker can inject arbitrary domain events into virt-handler, causing it to take incorrect lifecycle actions, corrupt VM state in the Kubernetes API, or crash — resulting in sustained denial of VM management services for all virtual machines on the affected node. Additionally, the same symlink following flaw allows virt-handler to apply file ownership or permission changes to unintended host paths.", "affected": [ { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.12", "packageName": "container-native-virtualization/virt-handler", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1791522624", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.13", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1786346596", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.14", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1786309624", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.15", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1786347656", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.16", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1786030071", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.17", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1786348529", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.18", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1786130068", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.19", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1786334215", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.20", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1785831334", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.21", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1785829701", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] }, { "vendor": "Red Hat", "product": "Red Hat Container Native Virtualization 4.22", "packageName": "container-native-virtualization/virt-handler-rhel9", "collectionURL": "https://catalog.redhat.com/software/containers/", "defaultStatus": "affected", "versions": [ { "version": "1785140336", "status": "unaffected", "versionType": "rpm", "lessThan": "*" } ] } ] } } }
