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.
AI Analysis
Technical Summary
The advisory covers two security fixes in the Delve debugger for Go on Red Hat Enterprise Linux 10. The first vulnerability (CVE-2026-27137) involves incorrect enforcement of email constraints in the crypto/x509 package. The second (CVE-2026-25679) concerns incorrect parsing of IPv6 host literals in the net/url package. These flaws could potentially impact the security of applications relying on these components. Red Hat has released updated Delve packages (version 1.25.2-3.el10_1) for multiple architectures to address these issues.
Potential Impact
The vulnerabilities may lead to incorrect handling of email constraints and IPv6 host literals, potentially causing security policy bypass or incorrect validation in applications using the affected packages. The advisory rates the impact as Important but does not provide detailed CVSS scores or explicit exploitation details. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released updated Delve packages for Red Hat Enterprise Linux 10 and its variants that fix these vulnerabilities. Users should apply the available updates as described in the Red Hat advisory RHSA-2026:8842 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patches.
