GHSA-M2WJ-X8QH-WQCV
Vulnerability from github – Published: 2024-10-29 03:31 – Updated: 2024-10-30 18:30In 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().

}
Mitigation
Choose a language that provides automatic memory management.
Mitigation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Use a static analysis tool to find double free instances.
No CAPEC attack patterns related to this CWE.
