Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已修复 Linux 内核中的下列漏洞：idpf: cleanup remaining SKBs in PTP flows When the driver requests Tx timestamp value, one of the first steps is to clone SKB using skb_get.
    It increases the reference counter for that SKB to prevent unexpected freeing by another component.
    However, there may be a case where the index is requested, SKB is assigned and never consumed by PTP flows
    - for example due to reset during running PTP apps. Add a check in release timestamping function to verify if the SKB assigned to Tx timestamp latch was freed, and release remaining SKBs. (CVE-2025-40175)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
