Security Fix(es): * cmd/go: cmd/go: Arbitrary file write via malicious pkg-config directive (CVE-2025-61731) * 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 golang packages in Red Hat Enterprise Linux 10 contain two notable security vulnerabilities. CVE-2025-61731 involves an arbitrary file write vulnerability through a malicious pkg-config directive in the cmd/go tool, potentially allowing unauthorized file modifications. CVE-2026-25679 concerns incorrect parsing of IPv6 host literals in the net/url package, which could lead to incorrect URL handling. Red Hat has issued security updates for golang version 1.25.8-1.el10_1 across multiple architectures to address these vulnerabilities.
Potential Impact
Successful exploitation of CVE-2025-61731 could allow an attacker with limited privileges to write arbitrary files, potentially leading to privilege escalation or system compromise. CVE-2026-25679 could cause incorrect processing of IPv6 URLs, potentially affecting applications relying on the net/url package for network communications. Both vulnerabilities have high impact on confidentiality, integrity, and availability as indicated by the CVSS vector for CVE-2025-61731.
Mitigation Recommendations
Red Hat has released updated golang packages (version 1.25.8-1.el10_1) for Red Hat Enterprise Linux 10 that address these vulnerabilities. Users should apply these official updates promptly following Red Hat's guidance at https://access.redhat.com/articles/11258. No alternative mitigations or workarounds are specified in the advisory.
