"void *priv" of "esp_now_peer_info" struct does not seem to work in ESPNOW

[MrTC1277]

I use ESP-IDF, its version is ESP-IDF v5.0-dev-2332-ge498209ed2-dirty
I try to assign a value to "peer->priv" in the following way

esp_now_peer_info_t *peer = malloc(sizeof(esp_now_peer_info_t));
if (peer == NULL)
{
ESP_LOGE(TAG, "Malloc peer information fail");
esp_restart();
}
memset(peer, 0, sizeof(esp_now_peer_info_t));
peer->channel = CONFIG_ESPNOW_CHANNEL;
peer->ifidx = ESPNOW_WIFI_IF;
peer->encrypt = true;
peer_data.heartbeat=111;
peer_data.identity = 4;
peer->priv=malloc(sizeof(espnow_peer_data_t));
memcpy(peer->priv,&peer_data,sizeof(espnow_peer_data_t));
memcpy(peer->lmk, CONFIG_ESPNOW_LMK, ESP_NOW_KEY_LEN);
memcpy(peer->peer_addr, recv_cb.mac_addr, ESP_NOW_ETH_ALEN);
ESP_ERROR_CHECK(esp_now_add_peer(peer));

the “espnow_peer_data_t” is my custom structure

typedef struct 
{
    uint8_t identity;
    uint32_t heartbeat;
}espnow_peer_data_t;

I read the variables in the following way

esp_now_peer_info_t *peer_info;
espnow_peer_data_t *peer_data_point;

peer_info = malloc(sizeof(esp_now_peer_info_t));
esp_now_fetch_peer(true,peer_info);
peer_data_point = (espnow_peer_data_t *)peer_info->priv;
free(peer_info->priv);

The read value is incorrect and caused a restart due to the release of an incorrect memory
