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: drm/msm/a6xx: move     preempt_prepare_postamble after error check Move the call to preempt_prepare_postamble() after verifying     that preempt_postamble_ptr is valid. If preempt_postamble_ptr is NULL, dereferencing it in     preempt_prepare_postamble() would lead to a crash. This change avoids calling the preparation function     when the postamble allocation has failed, preventing potential NULL pointer dereference and ensuring     proper error handling. Patchwork: https://patchwork.freedesktop.org/patch/687659/ (CVE-2025-71124)

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

The remote Ubuntu 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8177-1 advisory.

    Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo Rizzo discovered that some AMD     Zen processors did not properly verify the signature of CPU microcode. This flaw is known as EntrySign. A     privileged attacker could possibly use this issue to cause load malicious CPU microcode causing loss of     integrity and confidentiality. (CVE-2024-36347)
