Description OSIDB Bzimport 2026-09-16 12:01:41 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iio: pressure: dps310: fix NULL pointer dereference on ACPI probe

When the device is enumerated through its ACPI HID (IFX3100),
i2c_client_get_device_id() returns NULL: the ACPI-derived client name
does not match the driver's i2c_device_id table. dps310_probe() then
dereferences that NULL pointer in "iio->name = id->name" and crashes the
kernel during probe.

The IIO device name is always "dps310", so set it directly and drop the
now-unused device-id lookup.
