AI Analysis
Technical Summary
This advisory addresses two security vulnerabilities affecting Grafana as packaged in Red Hat Enterprise Linux 10. CVE-2026-32282 is a flaw in the golang internal syscall unix package where the Root.Chmod function can follow symlinks outside the root directory, potentially leading to unauthorized file permission changes. CVE-2026-32283 is a denial of service vulnerability in the Go crypto/tls package caused by processing multiple TLS 1.3 key update messages. Both vulnerabilities originate from underlying Golang libraries used by Grafana. Red Hat has released updated Grafana packages for multiple architectures in RHEL 10 to fix these issues.
Potential Impact
The impact includes potential unauthorized file permission changes due to symlink traversal (CVE-2026-32282) and denial of service conditions via TLS 1.3 key update message handling (CVE-2026-32283). Red Hat classifies the security impact as Important, indicating a high severity but not critical. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released updated Grafana packages for Red Hat Enterprise Linux 10 that address these vulnerabilities. Users should apply the provided security update as detailed in the Red Hat advisory RHSA-2026:11712 and the referenced update article (https://access.redhat.com/articles/11258). No additional mitigation steps are indicated beyond applying the official update.
