Q: Given the following code slice:
```
CWE-457___CVE-2024-31744.c___1-98___28.c_vul.c
1 static int jpc_dec_process_sod(jpc_dec_t *dec, jpc_ms_t *ms)
3 	jpc_dec_tile_t *tile;
8 	if (!(tile = dec->curtile)) {
12 	if (!tile->partno) {
13 		if (!jpc_dec_cp_isvalid(tile->cp)) {
16 		if (jpc_dec_cp_prepare(tile->cp)) {
19 		if (jpc_dec_tileinit(dec, tile)) {
25 	if (dec->pkthdrstreams) {
28 		if (!(tile->pkthdrstream = jpc_streamlist_remove(dec->pkthdrstreams, 0))) {

```
which has a vulnerability among CWE-457 and among lines:
```
28 		if (!(tile->pkthdrstream = jpc_streamlist_remove(dec->pkthdrstreams, 0))) {
```
Please generate five possible patches for the vulnerability.
