CVE-2024-57908

Kernel stack disclosure via uninitialized KMX61 buffer

Published Jan 19, 2025 · Updated May 11, 2026

Information disclosure in the KMX61 IIO driver in the Linux kernel allows local users to read uninitialized kernel stack data via buffered sensor output. The triggered-buffer handler fills only active-channel elements of its local array, then copies the entire array to user space without initializing the remaining elements. Access requires a system using the KMX61 sensor driver and a triggered IIO buffer; disclosed bytes are limited to residual kernel stack contents.
