AI Analysis
Technical Summary
This advisory covers three security vulnerabilities affecting Grafana as packaged in Red Hat Enterprise Linux 8.8. The issues stem from underlying Go language libraries: CVE-2025-61729 involves a denial of service caused by excessive resource consumption via crafted certificates in crypto/x509; CVE-2025-61728 involves excessive CPU consumption when building archive indexes in archive/zip; and CVE-2025-61726 involves memory exhaustion during query parameter parsing in net/url. These vulnerabilities could lead to denial of service conditions due to resource exhaustion. Red Hat has released updated Grafana packages (version 7.5.15-9.el8_8) to address these flaws.
Potential Impact
The vulnerabilities can cause denial of service through excessive CPU or memory consumption when processing specially crafted input related to certificates, ZIP archives, or URL query parameters. This could disrupt the availability of Grafana services on affected Red Hat Enterprise Linux 8.8 systems.
Mitigation Recommendations
Red Hat has released updated Grafana packages (7.5.15-9.el8_8) for Red Hat Enterprise Linux 8.8 that fix these vulnerabilities. Users should apply these official updates as described in the Red Hat advisory (RHSA-2026:3838) to remediate the issues. No additional mitigation steps are indicated beyond applying the vendor-provided update.
