AI Analysis
Technical Summary
Red Hat Product Security issued an important security advisory (RHSA-2026:3835) for Grafana in Red Hat Enterprise Linux 9.4 EUS, addressing three vulnerabilities tracked as CVE-2025-61726, CVE-2025-61728, and CVE-2025-61729. The vulnerabilities stem from Go language libraries used by Grafana: a denial of service via crafted certificates in crypto/x509 (CVE-2025-61729), excessive CPU consumption in archive/zip when building archive indexes (CVE-2025-61728), and memory exhaustion in query parameter parsing in net/url (CVE-2025-61726). These issues can cause resource exhaustion leading to denial of service conditions. Red Hat has provided updated Grafana packages for multiple architectures and variants of RHEL 9.4 to fix these vulnerabilities.
Potential Impact
The vulnerabilities can cause denial of service through excessive CPU or memory consumption when processing maliciously crafted inputs related to certificates, zip archives, or URL query parameters. This can degrade system performance or cause Grafana services to become unresponsive. No known exploits in the wild have been reported at the time of this advisory.
Mitigation Recommendations
Red Hat has released updated Grafana packages for Red Hat Enterprise Linux 9.4 Extended Update Support that address these vulnerabilities. Users should apply the available security updates as detailed in Red Hat advisory RHSA-2026:3835 and the referenced update article (https://access.redhat.com/articles/11258). No additional mitigation steps are indicated beyond applying the official patches.
