- Summary
- pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: nuvoton: fix a double free in ma35pinctrldtnodetomapfunc()
'newmap' is allocated using devm* which takes care of freeing the allocated data on device removal, call to
.dt_free_map = pinconf_generic_dt_free_mapdouble frees the map as pinconfgenericdtfreemap() calls pinctrlutilsfree_map().
Fix this by using kcalloc() instead of auto-managed devm_kcalloc().
