CVE-2024-50071 Information

Description

In the Linux kernel the following vulnerability has been resolved:

pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()

’new_map’ is allocated using devm_ which takes care of freeing the allocated data on device removal call to

.dt_free_map = pinconf_generic_dt_free_map

double frees the map as pinconf_generic_dt_free_map() calls pinctrl_utils_free_map().

Fix this by using kcalloc() instead of auto-managed devm_kcalloc().
