The remote Ubuntu 25.10 / 26.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8473-1 advisory.

    It was discovered that containerd incorrectly handled HTTP/2 SETTINGS frames. A remote attacker could     possibly use this issue to cause containerd to enter an infinite loop, resulting in a denial of service.
    (CVE-2026-33814)

    Jakub Ciolek and Kyle Elliott discovered that containerd incorrectly handled group parsing when creating     containers from images. An attacker could possibly use this issue to cause containerd to consume excessive     memory, resulting in a denial of service. (CVE-2026-47262)

    Henry Beberman and Robert Prast discovered that containerd incorrectly validated image references when     importing container checkpoints. An attacker could possibly use this issue to poison the local image cache     and execute arbitrary code in other pods. (CVE-2026-50195)

    Robert Prast discovered that containerd incorrectly propagated labels from image configurations to     containers. An attacker could possibly use this issue to execute arbitrary code on the host.
    (CVE-2026-53488)

    Yuming Zhang, Song Li, Sangwon Ryu, Henry Beberman, Robert Prast, Kyle Elliott and Zhenchen Wang     discovered that containerd incorrectly validated symlinked paths when restoring container checkpoints. An     attacker could possibly use this issue to read arbitrary files on the host, resulting in information     disclosure. (CVE-2026-53489)

    Robert Prast discovered that containerd incorrectly trusted device interface annotations when restoring     container checkpoints. An attacker could possibly use this issue to bypass resource allocation     restrictions and inject devices or host mounts into a container. (CVE-2026-53492)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
