CVE-2024-50071

Kernel memory corruption via device-tree map double-free

Published Oct 29, 2024 · Updated May 11, 2026

Double-free in the Nuvoton MA35 pin-control driver in Linux 6.11 through 6.11.4 allows local users to corrupt kernel memory. ma35_pinctrl_dt_node_to_map_func() allocates new_map with device-managed memory, while pinconf_generic_dt_free_map() frees the same map before device teardown frees it again. Reachability is limited to systems using the Nuvoton MA35 pin controller and affected driver; the corruption can crash the kernel or enable code execution.
