The remote Ubuntu 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8707-1 advisory.

    It was discovered that primitive decoders in openCryptoki produced integer underflows when the encoded     length was zero. An attacker could possibly use this issue to trigger out-of-bounds reads.
    (CVE-2026-40253)

    It was discovered that openCryptoki incorrectly handled symlinks. An attacker in the token-group could     possibly use this issue to achieve privilege escalation or access sensitive information. (CVE-2026-23893)

    It was discovered that the CKM_ECDH_AES_KEY_WRAP implementation had a heap buffer overflow vulnerability.
    An attacker could possibly use this issue to trigger heap corruption, or denial-of-service.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2026:0291-1 advisory.

    - CVE-2026-22791: Fixed supplying malformed compressed EC public key can lead to heap corruption or     denial-of-service (bsc#1256673).

Note that Nessus has not tested for this issue 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.

  - openCryptoki is a PKCS#11 library and tools for Linux and AIX. In 3.25.0 and 3.26.0, there is a heap     buffer overflow vulnerability in the CKM_ECDH_AES_KEY_WRAP implementation allows an attacker with local     access to cause out-of-bounds writes in the host process by supplying a compressed EC public key and     invoking C_WrapKey. This can lead to heap corruption, or denial-of-service. (CVE-2026-22791)

Note that Nessus relies on the presence of the package as reported by the vendor.
