Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 已解決 Linux 核心中的下列弱點：seg6: separate dst_cache for input and output paths in seg6 lwtunnel The seg6 lwtunnel uses a single dst_cache per encap route, shared between seg6_input_core() and seg6_output_core(). These two paths can perform the post-encap SID lookup in different routing contexts (e.g., ip rules matching on the ingress interface, or VRF table separation).
    Whichever path runs first populates the cache, and the other reuses it blindly, bypassing its own lookup.
    Fix this by splitting the cache into cache_input and cache_output, so each path maintains its own cached dst independently. (CVE-2026-31668)

請注意，Nessus 依賴供應商報告的套件存在。
