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：vduse: hold vduse_lock across IDR lookup in open path vduse_dev_open() looks up struct vduse_dev through the IDR and then acquires dev->lock only after vduse_lock has been dropped. This leaves a window where a concurrent VDUSE_DESTROY_DEV can remove the same object from the IDR and free it before the open path locks the device, leading to a use-after-free. Close this race by keeping vduse_lock held until dev->lock has been acquired in the open path, matching the lock ordering already used by the destroy path. (CVE-2026-74313)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
