CVE-2026-45683 | BDVDB-2026-337354 Detail

open-telemetryopentelemetry-ebpf-instrumentation

Description#

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.

Impact#

Per CVSS v3.1: confidentiality impact low, integrity impact none, availability impact none. Attack vector: local.

Weaknesses#

CWE-127 Buffer Under-read
CWE-200 Exposure of Sensitive Information to an Unauthorized Actor
