CVE-2026-45683
OpenTelemetry eBPF Instrumentation: Java TLS ioctl kprobe allows kernel memory disclosure
CVSS Score
3.8

EPSS Percentile
0th
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.
