This medium-severity CVE scores 6.2 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

opentelemetry-ebpf-profiler: Unprivileged process can trigger a denial of service on the ebpf-profiler agent

Summary

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.
