Doc Text:	A flaw was found in the Linux kernel's ROHM BM1390 Industrial I/O (IIO) sensor driver. The driver fails to propagate error status codes when a read operation fails, unconditionally returning success. A local user querying the sensor can receive invalid or uninitialized measurement data without an error notification when a hardware read fails.	Story Points:	---

Description OSIDB Bzimport 2026-10-18 15:55:48 UTC

In the Linux kernel, the following vulnerability has been resolved:

iio: pressure: rohm-bm1390: Return error when read fails

The data reading function ignores the cached error value, and
unconditionally returns 0. Return cached 'ret' -value after stopping
the measurement so user knows if read failed and data is garbage.
