containerd is an open-source container runtime. Prior to 1.7.35, 2.0.12, 2.2.8, and 2.3.5, containerd's layer unpack handler repeatedly traverses directories for certain opaque whiteout configurations. A malicious image layer can trigger repeated directory traversals while opaque whiteouts are processed. Pulling or importing the image can consume CPU, delay container startup, and reduce image-pull concurrency for unrelated deployments. This issue is fixed in versions 1.7.35, 2.0.12, 2.2.8, and 2.3.5.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-150509 advisory.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4923-1 advisory.

    - CVE-2026-39882: go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp: Memory exhaustion via     uncapped HTTP       response body reading (bsc#1274214).
    - CVE-2026-47262: Denial of Service (DoS) condition via a maliciously crafted image (bsc#1268441).
    - CVE-2026-53493: a crafted OCI index graph can force very high CPU/memory usage during PullImage (before     container       start), causing long ContainerCreating stalls and, at larger sizes, node/runtime instability     (bsc#1282669).
    - CVE-2026-53495: CRI ExecSync Goroutine Leak Leads to Node-Level Denial of Service (bsc#1280007).
    - CVE-2026-95838: github.com/containerd/containerd: processing of certain image layers causes superlinear     time       complexity in unpack handler and can lead to DoS (bsc#1285124).

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
