SCA: security update for go.opentelemetry.io/obi (GHSA-vvmg-8mjr-g6q3)

medium Tenable Self-Hosted Container Security Plugin ID 442116

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. 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 iov_iter.count as the copy length. When log injection is enabled, a
 crafted multi-segment writev call can make OBI read and overwrite memory beyond the first segment. This
 issue has been patched in version 0.9.0. (CVE-2026-45684)

Solution

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