Why it matters

The Linux kernel vulnerability CVE-2026-98659 has been resolved, but may have allowed incorrect data to be reported as valid.

• Verify data integrity in iio: pressure: rohm-bm1390 driver
• Review Linux kernel patch notes for CVE-2026-98659

Technical summary

The iio: pressure: rohm-bm1390 driver in the Linux kernel has been updated to correctly return error values when data reading fails. Previously, the driver ignored cached error values and unconditionally returned 0, potentially leading to incorrect data being reported as valid. The update improves data integrity and accuracy in the driver by ensuring that error values are correctly propagated and handled. This change is important for Linux kernel developers and maintainers, as it helps prevent potential issues with data quality and system reliability.
