Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： iio: pressure: dps310：修复 ACPI 探测过程中的空指针解引用问题 当设备通过其 ACPI HID（IFX3100）被枚举时， 会返回 NULL：因为由 ACPI 派生的客户端名称与驱动中的 表不匹配。随后， 在赋值语句 中解引用了该 NULL 指针，导致内核在探测阶段发生崩溃。 由于 IIO 设备名称始终为 "dps310"，因此可以直接设置该名称，并移除现在已不再使用的设备 ID 查找逻辑。

Vulnerability Title
iio: pressure: dps310: fix NULL pointer dereference on ACPI probe
Source: CVE Program / CVE List V5
Vulnerability Description
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.
