CVE-2024-57906

Local information disclosure via uninitialized triggered buffer

Published Jan 19, 2025 · Updated May 23, 2026

Information disclosure in the Linux TI ADS8688 ADC driver allows local users to read uninitialized kernel stack data through IIO buffers. The triggered-buffer handler fills only active-channel elements in its local buffer array, then copies the entire uninitialized array to user space. Access requires a local account and a system using the TI ADS8688 ADC driver with a triggered IIO buffer; exposed bytes can disclose residual kernel memory.
