In the Linux kernel, the following vulnerability has been resolved: iio: adc: ade9000: handle Phase C dip events in IRQ1 handler… (CVE-2026-98675)
Description
A vulnerability in the Linux kernel's ADE9000 ADC driver was resolved by correcting the handling of Phase C dip events in the IRQ1 handler. The issue was due to an off-by-one error in scanning event bits, which caused the highest event bit (bit 25) representing Phase C dip events to be ignored and never reported.

Technical Analysis
The Linux kernel ADE9000 ADC driver had a vulnerability where the constant defining the upper bound for scanning STATUS1 event bits was set to 25, excluding the highest event bit ADE9000_ST1_DIPC_BIT (bit 25). This omission meant Phase C dip events were not detected or reported. The fix involved increasing the scanning upper bound to 26, ensuring bit 25 is included and Phase C dip events are properly handled in the IRQ1 handler.
Potential Impact
Phase C dip events were not reported due to the scanning boundary error, potentially causing incomplete or inaccurate event handling in systems relying on the ADE9000 ADC driver. There is no indication of direct exploitation or broader system compromise from this issue.
Mitigation Recommendations
A fix has been applied to the Linux kernel to correct the event bit scanning boundary in the ADE9000 ADC driver. Users should update to the fixed kernel version containing this patch. No other mitigation actions are indicated.
