SCA: security update for go.opentelemetry.io/obi (GHSA-r6c9-g6q5-qrf9)

medium Tenable Cloud Security Plugin ID 442120

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 read beyond
 the fallback buffer and leak adjacent memory into telemetry. This issue has been patched in version 0.9.0.
 (CVE-2026-45681)

Solution

Update the go.opentelemetry.io/obi library and its related packages to version 0.9.0 or later.
