### Description I think that a memory leak accur when call **get_uri_params** function to get the params in Invite RURI. If RURI haven't params I don't see memory leaking, but yes if RURI have one or more params. <!-- Explain what you did, what you expected to happen, and what actually happened. -->

### Troubleshooting

#### Reproduction

1. In kamailio script load siputils module; 2. Invoke get_uri_params in request_route; 3. Make call traffic with params in Invite RURI; 4. Check memory using pkg_stat kamcmd command during call traffic. <!-- If the issue can be reproduced, describe how it can be done. -->

### Possible Solutions Looking the source code, it seems that the function doesn't free the memory allocated during parsing params (parse_params function), infact invoke the free procedure always with null value in params pointer.

I trying a simple modify saving the params poiter after parsing e use it in free function, than the memory don't accur!

``` int get_uri_param(struct sip_msg* _msg, char* _param, char* _value) { str *param, t; pv_spec_t* dst; pv_value_t val;

param_hooks_t hooks; param_t* params; param_t* parsed_params; // ----------------------> pointer declaretion

param = (str*)_param; dst = (pv_spec_t *) _value;

if (parse_sip_msg_uri(_msg) < 0) { LM_ERR("ruri parsing failed\n"); return -1; }

t = _msg->parsed_uri.params;

if (parse_params(&t, CLASS_ANY, &hooks, &params) < 0) { LM_ERR("ruri parameter parsing failed\n"); return -1; } parsed_params = params; // ---------------------> pointer assignment

while (params) { if ((params->name.len == param->len) && (strncmp(params->name.s, param->s, param->len) == 0)) { memset(&val, 0, sizeof(pv_value_t)); val.rs.s = params->body.s; val.rs.len = params->body.len; val.flags = PV_VAL_STR; dst->setf(_msg, &dst->pvp, (int)EQ_T, &val); goto found; } else { params = params->next; } } free_params(parsed_params); // -----------------------> use parsed_pointer to free memory return -1;

found: free_params(parsed_params); // --------------------> use parsed_pointer to free memory return 1; } ``` <!-- If you found a solution or workaround for the issue, describe it. Ideally, provide a pull request with a fix. -->
