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, fix complex rules rehash error flow Moving rules from matcher to matcher should not fail.
    However, if it does fail due to various reasons, the error flow should allow the kernel to continue     functioning (albeit with broken steering rules) instead of going into series of soft lock-ups or some     other problematic behaviour. Similar to the simple rules, complex rules rehash logic suffers from the same     problems. This patch fixes the error flow for moving complex rules: - If new rule creation fails before it     was even enqeued, do not poll for completion - If TIMEOUT happened while moving the rule, no point trying     to poll for completions for other rules. Something is broken, completion won't come, just abort the rehash     sequence. - If some other completion with error received, don't give up. Continue handling rest of the     rules to minimize the damage. - Make sure that the first error code that was received will be actually     returned to the caller instead of replacing it with the generic error code. All the aforementioned issues     stem from the same bad error flow, so no point fixing them one by one and leaving partially broken code -     fixing them in one patch. (CVE-2025-39768)

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