- Issue
- An unprivileged process can easily trigger the processPIDEvents goroutine to be blocked indefinitely, preventing the goroutine from analyzing any new ELF file. The goroutine stays blocked in the openat2 syscall forever and the profiler can no longer work properly, it is a denial of service. Impact The impact is limited to denial-of-service on the ebpf-profiler agent: - There has to be a malicious workload albeit unprivileged. - No exfiltration of data. No loss of data. Fix Fixed in https://github.com/open-telemetry/opentelemetry-ebpf-profiler/commit/234b685cab31c2cb2f79e966caeab168bcc489e4. Fix is part of v.0.0.202622.
Recommended action: Upgrade to 0.0.202622 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
