  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: pressure: dps310: fix NULL pointer dereference on ACPI probe\n\nWhen the device is enumerated through its ACPI HID (IFX3100),\ni2c_client_get_device_id() returns NULL: the ACPI-derived client name\ndoes not match the driver's i2c_device_id table. dps310_probe() then\ndereferences that NULL pointer in \"iio->name = id->name\" and crashes the\nkernel during probe.\n\nThe IIO device name is always \"dps310\", so set it directly and drop the\nnow-unused device-id lookup.",
