Red Hat Security Advisory: grafana security update
This advisory addresses multiple security vulnerabilities affecting Grafana packages in Red Hat Enterprise Linux 8. The issues include a symlink traversal vulnerability in golang's internal syscall package (CVE-2026-32282) and two denial of service vulnerabilities in Go's crypto/tls and crypto/x509 packages (CVE-2026-32283 and CVE-2026-32280). Red Hat has released updated Grafana packages to remediate these vulnerabilities. The update is rated as important by Red Hat Product Security. No known exploits in the wild have been reported at this time.
AI Analysis
Technical Summary
Red Hat Enterprise Linux 8's Grafana packages are affected by three security vulnerabilities originating from underlying Go libraries. CVE-2026-32282 involves a Root.Chmod function in golang's internal syscall/unix package that can follow symlinks outside the intended root, potentially leading to unauthorized file permission changes. CVE-2026-32283 is a denial of service vulnerability triggered by multiple TLS 1.3 key update messages in the crypto/tls package. CVE-2026-32280 is another denial of service issue in the certificate chain building process within crypto/x509 and crypto/tls. Red Hat has issued updated packages (grafana-9.2.10-30.el8_10) across multiple architectures to address these issues.
Potential Impact
Successful exploitation of CVE-2026-32282 could allow unauthorized modification of file permissions via symlink traversal. CVE-2026-32283 and CVE-2026-32280 could enable denial of service conditions in applications using the affected Go crypto libraries, potentially disrupting service availability. No evidence of active exploitation in the wild has been reported. The overall security impact is rated as important by Red Hat.
Mitigation Recommendations
Red Hat has released updated Grafana packages for Red Hat Enterprise Linux 8 that address these vulnerabilities. Users should apply the provided security update as detailed in the Red Hat advisory RHSA-2026:11507 and the referenced article https://access.redhat.com/articles/11258. Applying these official patches is the recommended remediation. No additional mitigation actions are specified or required by the vendor.
