Vulnerability from github – Published: 2024-10-29 03:31 – Updated: 2024-10-30 18:30

Details

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().

Severity

7.8 (High)
