Summary
OpenTelemetry eBPF Instrumentation: Java TLS ioctl kprobe allows kernel memory disclosure
Details

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 bpfproberead instead of bpfproberead_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.
