Red Hat Security Advisory: delve security update
Delve is a debugger for the Go programming language. The goal of the project is to provide a simple, full featured debugging tool for Go. Delve should be easy to invoke and easy to use. Chances are if you're using a debugger, things aren't going your way. With that in mind, Delve should stay out of your way as much as possible. Security Fix(es): * crypto/x509: Incorrect enforcement of email constraints in crypto/x509 (CVE-2026-27137) * net/url: Incorrect parsing of IPv6 host literals in net/url (CVE-2026-25679) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
