Vulnerability from fkie_nvd - Published: 2024-06-21 11:15 - Updated: 2026-06-17 07:40
Severity
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: iio: adc: PAC1934: fix accessing out of bounds array index Fix accessing out of bounds array index for average current and voltage measurements. The device itself has only 4 channels, but in sysfs there are "fake" channels for the average voltages and currents too.
