No confirmed in-the-wild exploitation; assess based on exposure
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，已修复以下漏洞： usb: xusbatm：不要依赖 id 表指针算术运算 当涉及动态 ID 时，当前代码存在缺陷；在这种情况下， 函数的 参数位于堆上，而指针算术运算会计算出严重越界的索引。由于 动态初始化 USB 设备 ID，因此可以直接使用 字段。 即使经过上述转换， 仍然无法支持动态 ID，因此还需设置 标志。

Vulnerability Title
usb: xusbatm: don't rely on id table pointer arithmetic
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
usb: xusbatm: don't rely on id table pointer arithmetic
The current code is broken when dynamic ID is involved; in such cases
usb_device_id parameter of probe lives on the heap and the pointer
arithmetic will get an index that is wildly out of bound. xusbatm
initialize the USB device IDs dynamically so it can just use driver_info
too.
Even with conversion, xusbatm still cannot support dynamic IDs, so also set
no_dynamic_id.
