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.(CVE-2026-12080)","affected":[{"package":{"ecosystem":"openEuler:22.03-LTS-SP4","name":"qemu","purl":"pkg:rpm/openEuler/qemu&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.0-120.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["qemu-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-block-curl-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-block-iscsi-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-block-rbd-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-block-ssh-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-debuginfo-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-debugsource-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-guest-agent-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-hw-usb-host-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-img-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-system-aarch64-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-system-arm-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-system-riscv-6.2.0-120.oe2203sp4.aarch64.rpm","qemu-system-x86_64-6.2.0-120.oe2203sp4.aarch64.rpm"],"noarch":["qemu-help-6.2.0-120.oe2203sp4.noarch.rpm"],"src":["qemu-6.2.0-120.oe2203sp4.src.rpm"],"x86_64":["qemu-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-block-curl-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-block-iscsi-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-block-rbd-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-block-ssh-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-debuginfo-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-debugsource-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-guest-agent-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-hw-usb-host-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-img-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-seabios-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-system-aarch64-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-system-arm-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-system-riscv-6.2.0-120.oe2203sp4.x86_64.rpm","qemu-system-x86_64-6.2.0-120.oe2203sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4085"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12080"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H"}],"database_specific":{"severity":"High"}}
