In the Linux kernel, the following vulnerability has been resolved: iio: light: rohm-bu27034: Fix infinite delay on error When reading an… (CVE-2026-98661)
Description
A vulnerability in the Linux kernel's iio light driver for the rohm-bu27034 sensor caused an infinite delay when reading the integration time failed. The issue occurred because the error code was incorrectly used to compute sleep time, leading to an infinite delay. This has been fixed by defaulting to the smallest integration time if reading fails.

Technical Analysis
The Linux kernel's iio light driver for the rohm-bu27034 sensor had a flaw where failure to read the integration time resulted in using the error code as the sleep time, causing an infinite delay. The fix involves using the smallest integration time as a fallback default to prevent this infinite delay condition.
Potential Impact
This vulnerability could cause the affected driver to hang indefinitely due to an infinite delay when an error occurs reading the integration time. This may impact system responsiveness or sensor functionality but does not indicate direct code execution or privilege escalation.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to address this issue by using the smallest integration time as a default when reading the integration time fails. Users should update to the fixed kernel version once available. Patch status is not explicitly confirmed in the input; check the vendor advisory for current remediation guidance.
