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

Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Published

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.

### 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](https://github.com/open-telemetry/opentelemetry-ebpf-profiler/releases/tag/v0.0.202622).
