CVE-2026-45685: Opentelemetry Ebpf Instrumentation

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.1.0 to before version 0.9.0, malformed MongoDB wire messages can trigger uncaught panics in the MongoDB TCP parser, allowing a remote unauthenticated attacker to crash the telemetry agent and cause a denial of service. The parser operates on raw attacker-controlled network payloads before the input is fully validated, so a single crafted message can terminate telemetry collection for the affected process or node. This issue has been patched in version 0.9.0.

Affected products

• Opentelemetry Ebpf Instrumentation: from 0.1.0, before 0.9.0 (fixed in 0.9.0)
