This vulnerability allows an attacker to crash the gateway service, potentially disrupting network traffic and application connectivity.","exploitability":"Exploitation appears moderately difficult as it requires crafting specific input data that triggers the sorting comparator with strict-weak-ordering violation, but no public exploit references are available and the vulnerability is in a backend sorting operation rather than a direct input parsing routine.","blast_radius":"If exploited, this vulnerability could cause significant disruption to network services that rely on DataPower Gateway for traffic management, potentially leading to complete service outages for applications depending on the gateway's functionality.","remediation":"Upgrade to IBM DataPower Gateway 10.5.0.23, 10.6.7, 10.6.0.11, or 11.0.0.3 to remediate this vulnerability.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["dos","gateway","memory"],"model":"garnet-coder","analyzedAt":"2026-10-16T09:26:51.974Z"}}
