CVE-2025-38547

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

iio: adc: axp20x_adc: Add missing sentinel to AXP717 ADC channel maps

The AXP717 ADC channel maps is missing a sentinel entry at the end. This causes a KASAN warning.

Add the missing sentinel entry.

This vulnerability does not affect Red Hat Enterprise Linux as the vulnerable AXP717 ADC driver code is not present in supported kernel packages. The flaw stems from an out-of-bounds read caused by a missing termination sentinel in channel mappings for specialized PMIC hardware. Exploitation would require a system equipped with this specific hardware, presenting no practical risk to enterprise deployments.
