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。

  - smb 客户端使 smbd_destroy() 调用 disable_work_sync(&info->post_send_credits_work) 在 smbd_destroy() 中我们可能会破坏内存因此最好等待 post_send_credits_work 不再待定且永远不会再次启动。实际上我刚在 drivers/infiniband/sw/rxe/rxe_verbs.c:1032 rxe_post_recv+0x1ee/0x480 使用 rxe: WARNING: CPU: 0 PID: 138 [rdma_rxe] ...

    queue_work(info->workqueue, &info->post_send_credits_work); (CVE-2025-39932)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
