CVSS 3.1
3.8 lowCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:NCVE-2026-45683
Low (3.8) in opentelemetry ebpf instrumentation. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in go.opentelemetry.io/obi 0.9.0.
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.
