CVE-2024-57912

Local kernel-memory disclosure via uninitialized buffer padding

Published Jan 19, 2025 · Updated May 11, 2026

Information disclosure in affected Linux kernel releases allows local users to read uninitialized bytes through the zpa2326 triggered buffer. The zpa2326_trigger_handler builds a sample containing pressure, temperature, padding, and a timestamp without initializing the padding. The path requires local access and a configured zpa2326 IIO device; disclosure is limited to bytes copied from the sample structure's padding.
