CVE-2022-49386

Service interruption via unreleased device-tree references

Published Feb 26, 2025 · Updated May 11, 2026

Resource leakage in the AM65 CPSW NUSS driver in affected Linux kernels allows local users to interrupt service through probe errors. The am65_cpsw_init_cpts() and am65_cpsw_nuss_probe() error paths retain references returned by of_get_child_by_name() instead of releasing them with of_node_put(). Reachability requires the TI K3 AM65 CPSW NUSS driver and its device-tree node to enter an initialization or probe error path; the published impact is limited to availability.
