Commit message

jira VULN-46557
cve CVE-2024-53141
commit-author Jeongjun Park <aha310510@gmail.com>
commit 35f56c554eb1b56b77b3cf197a6b00922d49033d

When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists, the values of ip and ip_to are slightly swapped. Therefore, the range check for ip should be done later, but this part is missing and it seems that the vulnerability occurs.

So we should add missing range checks and remove unnecessary range checks.
