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： 平台/x86：asus-wireless：当没有 ACPI 匹配时，使 probe 失败 由于 可以强制让任意设备匹配，即使它不在驱动支持的设备 ID 列表中，因此依赖设备 ACPI 伴随对象（companion object）存在的平台驱动必须验证该对象确实存在。 在 未找到匹配项时仍返回成功，导致遗留一个永远不会上报任何内容的输入设备（因为通知处理程序未安装）。更严重的是，当驱动被强制绑定到没有 ACPI 伴随对象的设备时，probe 仍然成功，并保存了一个 NULL

Vulnerability Title
platform/x86: asus-wireless: Fail probe when there is no ACPI match
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: platform/x86: asus-wireless: Fail probe when there is no ACPI match Every platform driver can be forced to match a device that does not match its list of device IDs because of device_match_driver_override(), so platform drivers that rely on the existence of a device ACPI companion object need to verify its presence. asus_wireless_probe() returns success when acpi_match_acpi_device() finds no match, leaving behind an input device that never reports anything because the notify handler is not installed. Worse, when the driver is force-bound to a device without an ACPI companion, probe still succeeds and stores a NULL companion pointer, which asus_wireless_remove() later passes to acpi_dev_remove_notify_handler(), leading to a NULL pointer dereference on unbind. Return -ENODEV when the device does not match the ID table. This also covers the missing-companion case, because acpi_match_acpi_device() rejects a NULL device. Perform the check before allocating any driver state, instead of after the input device has already been registered.
