Technical Summary
Red Hat Product Security issued an advisory (RHSA-2026:3838) for Grafana in Red Hat Enterprise Linux 8.8 addressing three security vulnerabilities originating from Golang components used by Grafana. These include CVE-2025-61729 (Denial of Service via crafted certificate in crypto/x509), CVE-2025-61728 (Excessive CPU consumption in archive/zip), and CVE-2025-61726 (Memory exhaustion in net/url query parsing). The vulnerabilities can cause denial of service conditions due to excessive resource consumption. Updated Grafana packages (version 7.5.15-9.el8_8) have been released to fix these issues. The advisory rates the impact as Important (high severity) but does not provide CVSS scores. No known exploits in the wild have been reported. The affected products include Red Hat Enterprise Linux 8.8 variants for x86_64 and ppc64le architectures.
Potential Impact
The vulnerabilities can lead to denial of service conditions by exhausting CPU or memory resources when processing specially crafted inputs such as certificates, zip archives, or URL query parameters. This could disrupt Grafana service availability on affected Red Hat Enterprise Linux 8.8 systems. No information about privilege escalation or data compromise is provided.
Mitigation Recommendations
Red Hat has released updated Grafana packages (version 7.5.15-9.el8_8) for Red Hat Enterprise Linux 8.8 that address these vulnerabilities. Users should apply these official updates promptly following Red Hat's guidance at https://access.redhat.com/articles/11258. No additional mitigation steps are specified or required beyond applying the vendor-provided patches.
