A local unprivileged user can exploit a vulnerability in the guest-ssh-add-authorized-keys command handler by manipulating symbolic links. This can occur either through a deterministic directory-symlink bypass or a Time-of-Check to Time-of-Use (TOCTOU) file-symlink race. Successful exploitation allows the attacker to gain ownership of arbitrary root-owned files or directories, leading to root access. This vulnerability requires an external management layer (e.g., libvirt) to trigger the affected code path.","score":7.3,"severity":"high","published":"2026-07-20T12:40:45.399Z","modified":"2026-10-30T05:41:40.329Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 9","platforms":[],"versions":[{"version":"17:10.1.0-17.el9_8.9","status":"unaffected","lessThan":"*","versionType":"rpm"}],"defaultStatus":"affected","cpes":["cpe:/a:redhat:enterprise_linux:9::appstream"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 10","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:10"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 6","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:6"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 7","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:7"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 7","platforms":[],"versions":[],"defaultStatus":"unaffected","cpes":["cpe:/o:redhat:enterprise_linux:7"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux 8","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:8"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"},{"vendor":"Red Hat","name":"Red Hat Enterprise Linux for NVIDIA 26","platforms":[],"versions":[],"defaultStatus":"unknown","cpes":["cpe:/a:redhat:enterprise_linux_nvidia:"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"},{"vendor":"Red Hat","name":"Red Hat OpenShift Container Platform 4","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/a:redhat:openshift:4"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"},{"vendor":"Red Hat","name":"Red Hat OpenShift Container Platform 4","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/a:redhat:openshift:4"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"},{"vendor":"Red Hat","name":"Red Hat OpenShift Container Platform 5","platforms":[],"versions":[],"defaultStatus":"affected","cpes":["cpe:/a:redhat:openshift:5"],"source":"redhat","url":"https://www.cve.org/CVERecord?id=CVE-2026-12080"}],"remediation":[{"text":"If the `guest-ssh-add-authorized-keys` command is not required, it can be disabled by adding it to the qemu-guest-agent block list (qemu-ga --block-rpcs).
