Red Hat Security Advisory: golang security update
The golang packages provide the Go programming language compiler. 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 contain two security flaws. CVE-2025-61731 involves an arbitrary file write vulnerability in the cmd/go tool triggered by a malicious pkg-config directive. CVE-2026-25679 concerns incorrect parsing of IPv6 host literals in the net/url package. Both vulnerabilities have been addressed in updated golang packages provided by Red Hat for versions 8.6 and 9.2 of their Enterprise Linux distribution.
Potential Impact
The arbitrary file write vulnerability could allow an attacker to write files arbitrarily, potentially leading to code execution or system compromise if exploited. The incorrect parsing of IPv6 host literals could cause unexpected behavior in applications relying on net/url, possibly leading to security bypass or denial of service. Red Hat rates the security impact as Important (high severity). There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released updated golang packages for Red Hat Enterprise Linux 8.6 and 9.2 that fix these vulnerabilities. Users should apply these official updates as detailed in Red Hat advisory RHSA-2026:7833 and RHSA-2026:7876. Refer to https://access.redhat.com/articles/11258 for update instructions. No additional mitigation steps are indicated beyond applying these patches.
