Technical Summary
The Red Hat security advisory RHSA-2026:3469 reports three vulnerabilities in the golang packages: CVE-2025-61728 causes excessive CPU consumption when building archive indexes in archive/zip; CVE-2025-61726 leads to memory exhaustion during query parameter parsing in net/url; and CVE-2025-61732 allows potential code smuggling via documentation comments in cmd/cgo. These vulnerabilities affect the Go compiler packages distributed with Red Hat Enterprise Linux 9.4 Extended Update Support on various architectures including x86_64, aarch64, s390x, and ppc64le. Red Hat has released updated golang packages (version 1.21.13-14.el9_4) to address these issues. The advisory references bugzilla entries for each CVE and directs users to apply the update as detailed in Red Hat's documentation.
Potential Impact
The vulnerabilities can lead to resource exhaustion conditions such as excessive CPU usage and memory exhaustion, potentially impacting system stability or availability when processing specially crafted inputs. Additionally, the code smuggling vulnerability in cmd/cgo could allow malicious code to be introduced via documentation comments, which may affect the integrity of builds. These issues pose a high security impact as rated by Red Hat, potentially enabling denial of service or code injection scenarios if exploited.
Mitigation Recommendations
Red Hat has released updated golang packages that fix these vulnerabilities. Users of Red Hat Enterprise Linux 9.4 Extended Update Support should apply the golang update to version 1.21.13-14.el9_4 or later as provided in the advisory RHSA-2026:3469. Detailed instructions for applying the update are available at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official update.
