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

  - net/mlx5: HWS, change error flow on matcher disconnect Currently, when firmware failure occurs during     matcher disconnect flow, the error flow of the function reconnects the matcher back and returns an error,     which continues running the calling function and eventually frees the matcher that is being disconnected.
    This leads to a case where we have a freed matcher on the matchers list, which in turn leads to use-after-     free and eventual crash. This patch fixes that by not trying to reconnect the matcher back when some FW     command fails during disconnect. Note that we're dealing here with FW error. We can't overcome this     problem. This might lead to bad steering state (e.g. wrong connection between matchers), and will also     lead to resource leakage, as it is the case with any other error handling during resource destruction.
    However, the goal here is to allow the driver to continue and not crash the machine with use-after-free     error. (CVE-2025-21751)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-948 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.48-1.

    We recommend that you upgrade your linux packages.
