Kernel vulnerability in Linux affecting AXP717 ADC channel maps

CVE-2025-38547

What is CVE-2025-38547?

A vulnerability in the Linux kernel was identified involving the AXP717 ADC channel maps, where a missing sentinel entry at the end of the channel maps results in a Kernel Address Sanitizer (KASAN) warning. This oversight can lead to unexpected behavior in the kernel's handling of ADC channel mappings, potentially impacting system stability and performance. It is crucial for system administrators and developers relying on the Linux kernel to address this by ensuring that all required sentinel entries are included in the ADC channel map configurations.
