Frequently Asked Questions

1

Which systems are exposed to this crash?

Systems using the DPS310 pressure sensor driver are exposed when the device is enumerated through the ACPI HID IFX3100. In that path, the ACPI-derived client name does not match the driver's I2C device-ID table.

2

What is required to trigger the issue?

The vulnerable probe path is reached when an IFX3100 device is probed through ACPI. No additional attacker-controlled input or permissions are described; the reported outcome is a kernel crash during driver probe.

3

How can I tell whether a system has encountered the vulnerability?

Affected systems crash during DPS310 driver probing because dps310_probe() dereferences a NULL device-ID pointer. The relevant deployment condition is ACPI enumeration using HID IFX3100.

4

What changes in the resolved code?

The fix sets the IIO device name directly to "dps310" rather than obtaining it from the I2C device-ID lookup. This avoids dereferencing the NULL result returned for the ACPI-enumerated device.
