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.

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

  - In the Linux kernel, the following vulnerability has been resolved: rxrpc: reject undecryptable rxkad     response tickets rxkad_decrypt_ticket() decrypts the RXKAD response ticket and then parses the buffer as     plaintext without checking whether crypto_skcipher_decrypt() succeeded. A malformed RESPONSE can therefore     use a non-block-aligned ticket length, make the decrypt operation fail, and still drive the ticket parser     with attacker-controlled bytes. Check the decrypt result and abort the connection with RXKADBADTICKET when     ticket decryption fails. (CVE-2026-31637)

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

The version of kernel-generic installed on the remote host is prior to 5.15.209 / 5.15.209_smp / 6.12.92 / 6.18.34. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2026-152-01 advisory.

    New kernel packages are available for Slackware 15.0 and -current to fix security issues.

The remote Ubuntu 14.04 LTS / Pro FIPS 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8548-1 advisory.

    It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when     handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43503)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8528-1 advisory.

    It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic     operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or     possibly escape a container. (CVE-2026-31431)

    It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer     operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in     the RxRPC networking subsystem when processing paged fragments. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43284, CVE-2026-43500)

    It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when     handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to     escalate privileges, or possibly escape a container. (CVE-2026-43503, CVE-2026-46300)

    Qualys discovered that a race condition existed in the ptrace subsystem of the Linux kernel when     privileged processes are exiting. An unprivileged local attacker could use this issue to expose sensitive     information. (CVE-2026-46333)
