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."}], "source": {"advisory": "GHSA-fjq3-ffvr-vm46", "discovery": "UNKNOWN"}}}}
