CVE-2024-57911

Kernel-memory disclosure via uninitialized IIO buffer

Published Jan 19, 2025 · Updated May 11, 2026

Information disclosure in the Linux kernel IIO dummy buffer allows local users to read kernel heap data through a triggered-buffer read. The buffer path allocates its data array with kmalloc, initializes only active channels, and then copies inactive-channel bytes to user space. Reachability requires a configured IIO dummy triggered buffer with inactive channels; the bounded consequence is disclosure of residual kernel-memory contents.
