What is CVE-2026-45676?

The OpenTelemetry eBPF Instrumentation features a flaw in its ELF parsing mechanism, where it improperly trusts section offsets and string offsets derived from executable files. This can lead to scenarios where a specially crafted local ELF file prompts the instrumentation to dereference corrupted section pointers or improperly access sections of string tables. As a consequence, this vulnerability can cause the instrumentation agent to experience unexpected shutdowns while it attempts to ascertain the process language. The issue has been resolved in version 0.9.0, providing users a timely solution to enhance their application security.
