netty-handler: netty-handler: IPv6 subnet rule bypass due to incorrect masking operation

A flaw was found in netty-handler, a component of the Netty network application framework. A remote attacker can exploit an incorrect masking operation in the IpSubnetFilterRule.compareTo function to bypass configured IPv6 subnet rules. This allows valid public IP addresses to circumvent intended...

SUSE CVE-2026-19566

Net::CIDR::Set versions before 0.23 for Perl allow memory exhaustion and malformed set ranges via unbounded IPv6 prefix lengths. The encode method accepts any prefix length matching 0|1-90-9 and passes it to width2bits, which builds the mask as '1' x $width + 8, one character per bit. The inc...
