  "details": "### Summary\n\nAn 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.\n\n### Impact\n\nThe impact is limited to denial-of-service on the ebpf-profiler agent:\n- There has to be a malicious workload albeit unprivileged.\n- No exfiltration of data. No loss of data.\n\n###  Fix\n\nFixed in https://github.com/open-telemetry/opentelemetry-ebpf-profiler/commit/234b685cab31c2cb2f79e966caeab168bcc489e4.\n\nFix is part of [v.0.0.202622](https://github.com/open-telemetry/opentelemetry-ebpf-profiler/releases/tag/v0.0.202622).",
