CVE-2026-45680: Opentelemetry Ebpf Instrumentation

High severity, CVSS 7.5. EPSS: 0.3% chance of exploitation in the next 30 days.

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, OBI replays BPF probe hits into histogram observations by looping once per recorded run count. On busy systems, the run-count delta can become very large, causing the metrics exporter to spend excessive CPU time in a tight loop every collection interval. This issue has been patched in version 0.9.0.

Affected products

• Opentelemetry Ebpf Instrumentation: before 0.9.0 (fixed in 0.9.0)
