Multiple vulnerabilities in perl-Net-CIDR-Lite can lead to IP ACL bypass due to improper validation of IP address formats and CIDR mask values. These include issues with trailing newlines or non-ASCII digits, extraneous leading zeros in CIDR masks, missing validation of IPv6 group counts, and mishandling of IPv4 mapped IPv6 addresses. The vulnerabilities affect SUSE Linux Enterprise Module for Development Tools 15 SP7 and related versions. No known exploits are reported in the wild. A security update addressing these issues has been released by the SUSE Product Security Team.

Net::CIDR::Lite versions before 0.24 for Perl does not properly validate IP address and CIDR mask inputs, which may allow IP ACL bypass. Inputs containing a trailing newline or non-ASCII digit characters pass the validators but are then re-encoded by the parser to a different address than the input string spelled.find() and bin_find() can match or miss addresses as a result. Example: my $cidr = Net::CIDR::Lite->new(); $cidr->add("::1\n/128"); $cidr->find("::1a"); # incorrectly returns true See also CVE-2026-45191.
