Technical 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().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
