建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
在 Linux 内核中，以下漏洞已得到修复： 追踪子系统：打开 options 文件时获取 trace_array 引用 问题描述： 文件在打开时并未获取其所代表选项对应的 的引用。这可能导致 use-after-free（释放后使用）内核崩溃：如果一个任务打开了某个 options 文件，而另一个任务删除了该选项所关联的 trace 实例，由于打开文件时未获取引用，无法阻止实例的删除操作，从而导致正在使用的 options 描述符被释放，引发内核崩溃。 技术细节： 由于 options 在系统启动时是动态创建的，

Vulnerability Title
tracing: Take trace_array reference when opening options file
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
tracing: Take trace_array reference when opening options file
The options files do not take the trace_array reference for the options
they represent. This could cause a use-after-free kernel crash if one of
these files is opened by one task and another task removes the instance
that the option is for. Because it doesn't take a reference upon opening,
it will not stop the removal which will free the options descriptor that
is being used.
As the options are somewhat dynamic in their creation at boot up, each
file represents a flag in the trace_array. The trace_array has an array of
indexes to represent each of these flags that is stored in the
trace_flags_index array. The address of the index array element is used to
pass to the inode->i_private pointer. Then that element is read which
holds the index (which represents the flag) and then the index is used to
calculate the trace_array descriptor from its trace_flags_index array.
One issue is that the index element can not be referenced until the
trace_array's reference is taken. To handle this, create a new helper
function called: trace_array_options_get() that will iterate all the
existing trace_arrays in the ftrace_trace_arrays list (under the
trace_types_lock), and compare the passed in address of the index element
with the entire array of the trace_array's trace_flags_index array.
If it matches, then up the corresponding trace_array's reference and
return.
