NVD Description

Note: Versions mentioned in the description apply only to the upstream alloy package and not the alloy package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

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.
