| 4 | +Subject: json_print: add NULL check before jsonw_string_field() in | ||
| 5 | + print_string() | ||
| 6 | + | ||
| 7 | +Static analyzer (Svace) reported a potential null pointer dereference | ||
| 8 | +in print_string(). Specifically, when both 'key' and 'value' are NULL, | ||
| 9 | +the function falls through to jsonw_string_field(_jw, key, value), | ||
| 10 | +which dereferences both pointers. | ||
| 11 | + | ||
| 12 | +Although comments suggest this case is unlikely, it is safer to | ||
| 13 | +explicitly guard against it. This patch adds a check to ensure | ||
| 14 | +both key and value are non-NULL before passing to jsonw_string_field(). | ||
| 15 | + | ||
| 16 | +This resolves: | ||
| 17 | +DEREF_AFTER_NULL: json_print.c:142 | ||
| 18 | + | ||
| 19 | +Found by Svace static analysis tool. | ||

| 4 | +Subject: netlink: add NULL check for get_string() in features.c | ||
| 5 | + | ||
| 6 | +Report of the static analyzer: | ||
| 7 | +Return value of a function 'get_string' is dereferenced at features.c:279 | ||
| 8 | +without checking for NULL, but it is usually checked for this function (6/7). | ||
| 9 | + | ||
| 10 | +Correct explained: | ||
| 11 | +Added NULL check for get_string() return value before passing to strcmp() | ||
| 12 | +to prevent potential NULL pointer dereference. This matches the behavior | ||
| 13 | +in other similar code paths where get_string() is used. | ||
| 14 | + | ||
| 15 | +Triggers found by static analyzer Svace. | ||
| 16 | + | ||
| 17 | +Fixes: a7a05af4a1ea ("netlink: add netlink handler for sfeatures (-K)") | ||
