Linux Kernel AXP717 ADC Channel Map Sentinel Entry Vulnerability

A vulnerability exists in the Linux kernel's handling of the AXP717 ADC channel maps within the AXP20X ADC driver. The issue arises because the channel map is missing a sentinel entry at the end, leading to a KASAN warning. This vulnerability affects the Linux kernel stable tree.

Impact

The absence of the sentinel entry can cause memory safety issues, potentially leading to out-of-bounds access or use-after-free vulnerabilities, as indicated by the KASAN warning.
