Summary
The TCP/IP networking module in Unisys ClearPath MCP systems with TCP-IP-SW 57.1 before 57.152, 58.1 before 58.142, or 59.1 before 59.172, when running a TLS 1.2 service, allows remote attackers to cause a denial of service (network connectivity disruption) via a client hello with a signature_algorithms extension above those defined in RFC 5246, which triggers a full memory dump.
Exploit prediction
1.54% chance of exploitation in the next 30 days, higher than 75% of all scored CVEs (FIRST EPSS, 2026-11-09).
