Doc Text:	A flaw was found in the Linux kernel's Analog Devices ADE9000 driver. An off-by-one error in the interrupt handler sets an incorrect upper bound when scanning device status events. Consequently, the driver fails to detect and report Phase C power dip events to the operating system, preventing monitoring applications from alerting administrators to power anomalies.

Description OSIDB Bzimport 2026-10-18 15:58:39 UTC

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

iio: adc: ade9000: handle Phase C dip events in IRQ1 handler

ADE9000_ST1_CROSSING_DEPTH is the exclusive upper bound for scanning the
STATUS1 event bits, so a value of 25 left out the highest event bit,
ADE9000_ST1_DIPC_BIT (bit 25). Phase C dip events were never reported.

Bump the value to 26 so bit 25 is scanned.
