The Grafana plugin for Performance Co-Pilot includes datasources for scalable time series from pmseries and Redis, live PCP metrics and bpftrace scripts from pmdabpftrace, as well as several dashboards. Security Fix(es): * golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root (CVE-2026-32282) * crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages (CVE-2026-32283) * crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building (CVE-2026-32280) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
The Grafana plugin for Performance Co-Pilot includes datasources and dashboards for time series and live metrics. This update addresses three security vulnerabilities originating from Go language libraries used by the plugin: CVE-2026-32282 allows Root.Chmod to follow symlinks outside the root directory, 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; CVE-2026-32280 is a denial of service vulnerability in certificate chain building within crypto/x509. These issues have been fixed in the updated grafana-pcp packages provided by Red Hat for Enterprise Linux 8.
Potential Impact
The vulnerabilities could allow an attacker to cause denial of service conditions via TLS key update message floods or certificate chain building failures, and potentially unauthorized file permission changes through symlink traversal. These issues impact the security and stability of systems running the affected grafana-pcp plugin on Red Hat Enterprise Linux 8. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated grafana-pcp packages for Red Hat Enterprise Linux 8 that address these vulnerabilities. Users should apply the security update as described in Red Hat advisory RHSA-2026:11514 and the referenced article https://access.redhat.com/articles/11258 to remediate the issues. No additional mitigation steps are indicated beyond applying the official update.
