Linux kernel netfilter ipset bitmap_ip_uadt missing range check
CVE-2024-53141 is a Linux kernel flaw in netfilter ipset, specifically in the bitmap_ip_uadt path. According to the provided description, when IPSET_ATTR_IP_TO is absent but IPSET_ATTR_CIDR is present, the handling of ip and ip_to becomes slightly swapped. As a result, the expected validation of the ip value is performed at the wrong point, leaving a required range check missing. The upstream fix adds the missing range validation and removes checks that were unnecessary in the affected logic. This is an input-validation error in kernel networking code that processes ipset bitmap IP update/add/test operations.
