Official description
OpenTelemetry eBPF Profiler is a production-scale agent for profiling applications across multiple programming languages. Starting in version 0.0.202527 and prior to version 0.0.202622, an unprivileged process can cause the profiler to open a nonregular mapping file, such as a FIFO, and block indefinitely, preventing further ELF analysis and causing a denial of service. Version 0.0.202622 contains a patch. No known workarounds are available.
