CVE-2024-53141 netfilter: ipset: add missing range check in bitmap_ip_uadt

What is CVE-2024-53141?

CVE-2024-53141 is a high-severity missing authorization vulnerability in Linux kernel, published on 6 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

In the Linux kernel, the following vulnerability has been resolved:

netfilter: ipset: add missing range check in bitmap_ip_uadt

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.
