# Linux kernel: ADE9000 driver misses Phase C dip events

In the Linux kernel's ADE9000 IIO ADC driver, the IRQ1 handler scanned one bit too few, so Phase C dip events were never reported. The sources describe a missed event report rather than memory corruption or code execution.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
