CVE-2026-45683: Opentelemetry Ebpf Instrumentation

Low severity, CVSS 3.8. EPSS: 0.2% 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, the Java TLS ioctl probe reads user-controlled ioctl pointers with bpf_probe_read instead of bpf_probe_read_user. An instrumented local process can therefore point OBI at kernel memory and cause that memory to be copied into telemetry. This issue has been patched in version 0.9.0.

Affected products

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