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.","epss":{"date":"2026-11-06","percentile":0.03344,"score":0.00139},"exploits":[],"kev":null,"metrics":[{"score":7.3,"severity":"high","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},{"score":7.3,"severity":"high","source":"NVD: secalert@redhat.com","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1794007041957,"publishedAt":1784551245399,"references":[{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:88421"},{"source":"CNA: redhat","tags":["vendor-advisory","x_refsource_REDHAT"],"url":"https://access.redhat.com/errata/RHSA-2026:95346"},{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-12080"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2499603"},{"source":"CNA: redhat","tags":[],"url":"https://gitlab.com/qemu-project/qemu/-/work_items/3929"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:88421"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/errata/RHSA-2026:95346"},{"source":"secalert@redhat.com","tags":[],"url":"https://access.redhat.com/security/cve/CVE-2026-12080"},{"source":"secalert@redhat.com","tags":[],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2499603"},{"source":"secalert@redhat.com","tags":[],"url":"https://gitlab.com/qemu-project/qemu/-/work_items/3929"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","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).
