Overview

CVE-2026-93124 is a known-severity vulnerability. It was published on September 17, 2026.

Technical 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 devi
