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

Summary The Java TLS ioctl probe reads user-controlled ioctl pointers with bpfproberead instead of bpfprobereaduser. An instrumented local process can therefore point OBI at kernel memory and cause that memory to be copied into telemetry. Details The vulnerable path is in...
