AI Analysis
Technical Summary
This advisory covers two security vulnerabilities affecting Grafana packages distributed with Red Hat Enterprise Linux 10. The first vulnerability (CVE-2026-32282) involves the golang internal syscall unix Root.Chmod function improperly following symbolic links outside the intended root directory, potentially leading to unauthorized file permission changes. The second vulnerability (CVE-2026-32283) is a denial of service issue in the Go crypto/tls package caused by processing multiple TLS 1.3 key update messages. Red Hat has released updated Grafana packages for multiple architectures to address these issues.
Potential Impact
The vulnerabilities could allow unauthorized modification of file permissions outside the intended root directory (CVE-2026-32282) and cause denial of service conditions via TLS 1.3 key update message handling (CVE-2026-32283). Red Hat rates the overall security impact as Important, indicating a high severity but not critical. There are no known exploits in the wild at the time of the advisory.
Mitigation Recommendations
Red Hat has released updated Grafana packages for Red Hat Enterprise Linux 10 that address these vulnerabilities. Users should apply the official updates as described in the Red Hat advisory RHSA-2026:11712 and the referenced article https://access.redhat.com/articles/11258. No additional mitigations are specified or required beyond applying the provided patches.
