In the Linux kernel, the following vulnerability has been resolved: iio: pressure: rohm-bm1390: Return error when read fails The data reading… (CVE-2026-98659)

The Linux kernel's iio pressure driver for rohm-bm1390 sensors had a flaw where the data reading function ignored cached error values and unconditionally returned 0. This meant that if a read operation failed, the function would not report the error, causing user-space to potentially process garbage data. The fix involves returning the cached error value after stopping the measurement, allowing the user to detect read failures.

User-space applications relying on the rohm-bm1390 sensor data could receive invalid data without any error indication, potentially leading to incorrect behavior or decisions based on corrupted sensor readings. There is no indication of further impact such as privilege escalation or denial of service.

A fix has been applied to the Linux kernel to return the cached error value when a read fails in the rohm-bm1390 driver. Users should update to a kernel version that includes this fix. Patch status is not explicitly confirmed in the provided data; users should consult the vendor or kernel release notes for the specific patch version and apply the update accordingly.
