CVE-2024-50071
Nuvoton Pinctrl Double-Free Linux Kernel Denial of Service
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().
