RHSA-2026:88421CVE-2026-12080qemu-kvm security, bug fix, and enhancement update Executive summary Red Hat has released a qemu-kvm update for Red Hat Enterprise Linux 9 that fixes a security flaw rated Important, along with some bug fixes and enhancements. The flaw is a local privilege escalation in the qemu-guest-agent component, and the vendor recommends applying the update to affected systems. Technical summary The advisory describes a local privilege escalation via a symlink attack in the guest-ssh-add-authorized-keys function of qemu-guest-agent, tracked as CVE-2026-12080. The advisory does not state the attack preconditions beyond it being a local attack, and it does not provide a CVSS score in the text, referring readers to the CVE page instead. The fixed package version is qemu-kvm-10.1.0-17.el9_8.9 (the build listed for each affected RHEL 9 channel), and the advisory lists no affected versions prior to that build. No workarounds are stated, and no exploitation in the wild is mentioned. Detection guidance is not stated, beyond the Red Hat Lightspeed patch analysis link for identifying affected systems. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
