GHSA-wp73-mwgf-4jq9: OpenTelemetry eBPF Instrumentation: Unsafe fastelf parsing allows malformed ELF to crash agent
Summary
OpenTelemetry eBPF Instrumentation (OBI) has a vulnerability where its ELF parser (a tool that reads executable file formats) blindly trusts offsets and metadata from binary files without checking if they're valid. A malicious or corrupted executable can cause OBI to crash when it tries to analyze what programming language a process uses, disrupting monitoring for other applications on the system.
