AI Analysis
Technical Summary
This Red Hat security advisory covers a set of vulnerabilities affecting Grafana and Go components in Red Hat Enterprise Linux 10. The primary Grafana vulnerability (CVE-2026-27877) involves information disclosure of data-source passwords through public dashboards. Two additional vulnerabilities in Go libraries are also addressed: a symlink traversal issue in internal/syscall/unix Root.Chmod (CVE-2026-32282) and a denial of service vulnerability in crypto/tls via multiple TLS 1.3 key update messages (CVE-2026-32283). Red Hat has released updated packages for Grafana version 10.2.6-26.el10_2 across multiple architectures to remediate these issues. The advisory references official Red Hat documentation for applying the update.
Potential Impact
The disclosed vulnerabilities could lead to unauthorized disclosure of sensitive data-source passwords in Grafana dashboards, potentially exposing credentials. The Go syscall vulnerability could allow unintended symlink traversal, possibly leading to privilege escalation or unauthorized file modifications. The TLS vulnerability could enable denial of service conditions in applications using the affected crypto/tls library. These issues collectively pose a high security risk if unpatched.
Mitigation Recommendations
Red Hat has released updated Grafana packages (version 10.2.6-26.el10_2) for Red Hat Enterprise Linux 10 and related variants to address these vulnerabilities. Users should apply these official updates promptly following Red Hat's guidance at https://access.redhat.com/articles/11258. No alternative mitigations or workarounds are indicated in the advisory. Patch status is confirmed as official-fix.
