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： 网络子系统：USB 驱动 pegasus：不应依赖 ID 表指针运算 当涉及动态 ID 时，当前代码存在缺陷；在此类情况下， 函数的 参数位于堆上，进行指针运算会导致索引严重越界。与其维护一个用于附加信息的侧表（side table），不如直接使用 中的 字段。 为此，动态 ID 解析代码也需要进行更新：改为仅向预留给动态 ID 的条目写入数据，并移除原有的异常循环逻辑。

Vulnerability Title
net: usb: pegasus: 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:
net: usb: pegasus: 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. Instead of
keeping a side table for additional information, use driver_info field of
the usb_device_id.
The dynamic ID parsing code needs to be updated for this; convert it to
just write to the reserved entry for dynamic ID and remove the weird loop.
