Exploitation
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： 无线网卡驱动 ath9k_htc：不再存储 usb_device_id 由于存在动态 ID 机制，usb_device_id 的生命周期无法保证长于 probe 函数。除 driver_data 之外，其余所有信息均可直接从 usb_device 结构体中获取，因此仅存储 driver_data 即可。

wifi: ath9k_htc: don't store usb_device_id
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k_htc: don't store usb_device_id
usb_device_id is not guaranteed to live longer than probe due to presence
of dynamic ID. All information apart from driver_data can be easily
retrieved from usb_device, so just store driver_data.
