CVE-2024-41069

Local kernel memory corruption via stale topology pointers

Published Jul 29, 2024 · Updated Aug 5, 2026

Use-after-free in the ASoC topology parser in Linux allows local users to corrupt kernel memory through stale DAPM route pointers. The soc_tplg_dapm_graph_elems_load function leaves route source, sink, and control pointers aimed into a topology firmware buffer that release_firmware later frees instead of preserving the strings. An unprivileged local user with access to the affected sound device can drive DAPM graph reevaluation, causing kernel-memory disclosure, corruption, or a panic.
