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.\n\nSecurity Fix(es):\n\n* encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal (CVE-2026-33818)\n\n* net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service (CVE-2026-56853)\n\n* crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages (CVE-2026-56862)\n\n* net/http: golang: golang: Denial of Service via crafted HTTP Range headers (CVE-2026-78667)\n\n* crypto/tls: golang: crypto/tls: Denial of Service via multiple ECH outer extension references (CVE-2026-97031)\n\n* crypto/x509: golang: crypto/x509: Man-in-the-middle attacks via untrusted intermediate certificates (CVE-2026-111943)\n\nBug Fix(es) and Enhancement(s):\n\n* Update Delve to 1.27 [rhel-10] (JIRA:Rocky Linux-219317)\n\nFor 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.", "severity": [{"type": "CVSS_V3", "score": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}], "affected": [{"package": {"ecosystem": "Rocky Linux:10", "name": "delve", "purl": "pkg:rpm/rocky-linux/delve?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:1.27.2-3.el10_3"}], "database_specific": {"yum_repository": "AppStream"}}]}, {"package": {"ecosystem": "Rocky Linux:10", "name": "delve-debuginfo", "purl": "pkg:rpm/rocky-linux/delve-debuginfo?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:1.27.2-3.el10_3"}], "database_specific": {"yum_repository": "AppStream"}}]}, {"package": {"ecosystem": "Rocky Linux:10", "name": "delve-debugsource", "purl": "pkg:rpm/rocky-linux/delve-debugsource?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:1.27.2-3.el10_3"}], "database_specific": {"yum_repository": "AppStream"}}]}, {"package": {"ecosystem": "Rocky Linux:10", "name": "delve-debuginfo", "purl": "pkg:rpm/rocky-linux/delve-debuginfo?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:1.27.2-3.el10_3"}], "database_specific": {"yum_repository": "AppStream"}}]}, {"package": {"ecosystem": "Rocky Linux:10", "name": "delve-debugsource", "purl": "pkg:rpm/rocky-linux/delve-debugsource?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:1.27.2-3.el10_3"}], "database_specific": {"yum_repository": "AppStream"}}]}, {"package": {"ecosystem": "Rocky Linux:10", "name": "delve", "purl": "pkg:rpm/rocky-linux/delve?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:1.27.2-3.el10_3"}], "database_specific": {"yum_repository": "AppStream"}}]}, {"package": {"ecosystem": "Rocky Linux:10", "name": "delve", "purl": "pkg:rpm/rocky-linux/delve?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:1.27.2-3.el10_3"}], "database_specific": {"yum_repository": "AppStream"}}]}, {"package": {"ecosystem": "Rocky Linux:10", "name": "delve-debuginfo", "purl": "pkg:rpm/rocky-linux/delve-debuginfo?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:1.27.2-3.el10_3"}], "database_specific": {"yum_repository": "AppStream"}}]}, {"package": {"ecosystem": "Rocky Linux:10", "name": "delve-debugsource", "purl": "pkg:rpm/rocky-linux/delve-debugsource?distro=rocky-linux-10&epoch=0"}, "ranges": [{"type": "ECOSYSTEM", "events": [{"introduced": "0"}, {"fixed": "0:1.27.2-3.el10_3"}], "database_specific": {"yum_repository": "AppStream"}}]}], "references": [{"type": "ADVISORY", "url": "https://errata.rockylinux.org/RLSA-2026:98086"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2548334"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2515827"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2515815"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2515839"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2548336"}, {"type": "REPORT", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2556068"}, {"type": "ADVISORY", "url": "https://access.redhat.com/errata/RHSA-2026:98086"}], "credits": [{"name": "Rocky Enterprise Software Foundation"}, {"name": "Red Hat"}], "database_specific": {"license": "CC-BY-4.0", "license_url": "https://creativecommons.org/licenses/by/4.0/", "source_advisory": "RHSA-2026:98086"}}
