CVE-2026-89933

Kernel crash via null device-ID dereference

Published Sep 16, 2026 · Updated Sep 16, 2026

NULL pointer dereference in the Linux DPS310 pressure-sensor driver crashes the kernel during ACPI probing of an IFX3100 device. The dps310_probe function asks i2c_client_get_device_id for an ID even though the ACPI-derived client name does not match the I2C ID table, then reads id->name from the returned null pointer. The failure requires DPS310 enumeration through ACPI HID IFX3100 and interrupts system availability at device probe; no network-triggered path is reported.
