CVE-2026-48496
Published:June 24, 2026
Updated:August 02, 2026
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).
