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

  - net: stmmac: Fix accessing freed irq affinity_hint In stmmac_request_irq_multi_msi(), a pointer to the     stack variable cpu_mask is passed to irq_set_affinity_hint(). This value is stored in     irq_desc->affinity_hint, but once stmmac_request_irq_multi_msi() returns, the pointer becomes dangling.
    The affinity_hint is exposed via procfs with S_IRUGO permissions, allowing any unprivileged process to     read it. Accessing this stale pointer can lead to: - a kernel oops or panic if the referenced memory has     been released and unmapped, or - leakage of kernel data into userspace if the memory is re-used for other     purposes. All platforms that use stmmac with PCI MSI (Intel, Loongson, etc) are affected. (CVE-2025-23155)

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