CVE-2026-45685

Summary: OpenTelemetry eBPF Instrumentation is affected by a remote DoS in its MongoDB parser. From version 0.1.0 up to before 0.9.0, malformed MongoDB wire messages can trigger uncaught panics in the MongoDB TCP parser, allowing an unauthenticated attacker to crash the telemetry agent and termin...

CVE-2026-45684 OpenTelemetry eBPF Instrumentation: Log enricher writev path can overread and overwrite user buffers

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.7.0 to before version 0.9.0, OBI's log enricher mishandles writev buffers by reading only the first iovec entry but using the total ioviter.count as the copy length. When log...

CVE-2026-45684

OpenTelemetry eBPF Instrumentation (OBI) log enricher vulnerability CVE-2026-45684: in versions 0.7.0–0.8.x, the writev path mishandles buffers by reading only the first iovec entry while using the total iov_iter.count for the copy length. When log injection is enabled, a crafted multi-segment wr...

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 bpfprobereaduser. An instrumented local process can therefore point OBI at kerne...

CVE-2026-45683

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 bpfprobereaduser. An instrumented local process can therefore point OBI at kerne...

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

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 bpfprobereaduser. An instrumented local process can therefore point OBI at kerne...

CVE-2026-45681 OpenTelemetry eBPF Instrumentation: CPU-mismatch fallback uses 256-byte buffer with 8KB size

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the per-CPU message-buffer fallback path uses a 256-byte backup buffer but preserves the original payload size, which can be up to 8KB. If a CPU mismatch occurs, OBI can...

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, OBI replays BPF probe hits into histogram observations by looping once per recorded run count. On busy systems, the run-count delta can become very large, causing the...

CVE-2026-45680

CVE-2026-45680 affects OpenTelemetry eBPF Instrumentation (OBI) prior to version 0.9.0. The root cause is an unbounded delta in calculateStats(), where bp.runCount − bp.prevRunCount is used without a cap, causing the exporter to loop over probe hits for large run-count deltas. This can lead to hi...

CVE-2026-45679 OpenTelemetry eBPF Instrumentation: Redis error text is exported in span status messages

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, OBI exports raw Redis error text as the span status message. Because Redis error replies can contain attacker-controlled or sensitive values, this behavior can exfiltrate...
