CVE-2026-45680: CWE-400: Uncontrolled Resource Consumption in open-telemetry opentelemetry-ebpf-instrumentation
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.
AI Analysis
Technical Summary
CVE-2026-45680 is an uncontrolled resource consumption vulnerability (CWE-400) in open-telemetry's opentelemetry-ebpf-instrumentation prior to version 0.9.0. The vulnerability occurs because the software replays BPF probe hits into histogram observations by looping once per recorded run count. On busy systems, the run-count delta can grow significantly, leading to excessive CPU consumption in a tight loop during each metrics collection interval. This behavior can degrade system performance due to high CPU usage. The issue is fixed in version 0.9.0.
Potential Impact
The vulnerability causes high CPU usage on affected systems during metrics collection intervals, potentially degrading system performance and availability. There is no impact on confidentiality or integrity. The CVSS 3.1 base score is 5.9 (medium severity), reflecting network attack vector, high attack complexity, no privileges required, no user interaction, and impact limited to availability.
Mitigation Recommendations
Upgrade to opentelemetry-ebpf-instrumentation version 0.9.0 or later, where this issue has been patched. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor advisory stating the fix is in version 0.9.0.
