Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，以下漏洞已得到修复： firewire 核心：修复 build_tree() 错误路径中的内存泄漏 在 build_tree() 函数的错误路径中，当函数返回时，局部链表中的节点实例可能未被释放。 每当在自身 ID 序列中检测到无效值时，每个已分配的节点实例要么位于链表中，要么位于其父节点的端口数组中。因此，可以从链表头部遍历，安全地释放已分配的节点实例。 在返回给调用者之前，使用 for_each_fw_node() 释放剩余的节点实例。

Vulnerability Title
firewire: core: fix memory leak in error path of build_tree()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
firewire: core: fix memory leak in error path of build_tree()
In the error path of build_tree(), node instances can remain in the local
linked list when the function returns.
Whenever an invalid value is detected in the self ID sequence, each
allocated node instance is either an entry in the linked list or an
entry in the ports array of its parent node. Therefore, the allocate
node instances can be safely released by traversing the linked list from
its head.
Release the remaining node instances with for_each_fw_node() before
returning to the caller.
