Base vector

AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

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.
