远程主机上安装的 F5 Networks BIG-IP 版本低于测试版本。因此，它受到 K000163638 公告中提及的一个漏洞影响。

    在 Linux 内核中，以下漏洞已修复：RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event() Sashiko points out the radix_tree itself is RCU safe, but nothing ever frees the mlx4_srq struct with RCU, and it isn't even accessed within the RCU critical section. It also will crash if an event is delivered before the srq object is finished initializing. Use the spinlock since it isn't easy to make RCU work, use refcount_inc_not_zero() to protect against partially initialized objects, and order the refcount_set() to be after the srq is fully initialized.(CVE-2026-46181)

Tenable 直接从 F5 Networks BIG-IP 安全公告中提取了前面的描述块。

请注意，Nessus 尚未测试此问题，而是只依据应用程序自我报告的版本号进行判断。
