Red Hat Security Advisory: grafana-pcp security update
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) 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 scalable time series and live metrics. Two security vulnerabilities were identified and fixed: CVE-2026-32282 involves a golang internal syscall (Root.Chmod) that can follow symbolic links outside the intended root, potentially leading to unauthorized file system access. CVE-2026-32283 is a denial of service vulnerability in Go's crypto/tls package caused by processing multiple TLS 1.3 key update messages. Red Hat has issued an update for grafana-pcp in Red Hat Enterprise Linux 10 to address these issues.
Potential Impact
The impact includes potential unauthorized file system access due to symlink traversal in the Root.Chmod syscall and denial of service conditions in TLS communications due to improper handling of multiple TLS 1.3 key update messages. These could affect system stability and security of encrypted communications on affected systems.
Mitigation Recommendations
Red Hat has released an updated package for grafana-pcp in Red Hat Enterprise Linux 10 that addresses these vulnerabilities. Users should apply the official Red Hat update as described in the advisory RHSA-2026:19136 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the update.
