- Summary
- Ash.Actions.Read.AsyncLimiter busy-spins a scheduler while awaiting slow async reads
- Details
-
Uncontrolled Resource Consumption vulnerability in ash-project ash lets a slow asynchronous read spin a scheduler thread at full CPU while the framework waits for it.
Ash.Actions.Read.AsyncLimiter.awaitatleastone/1 (lib/ash/actions/read/asynclimiter.ex) waited for concurrent async read tasks by polling each with Task.yield(task, 0) in a tight loop rather than blocking. While every outstanding task is still running (a slow related-data load or calculation), the loop returns immediately and repeats, busy-spinning and holding a BEAM scheduler at full CPU for the whole duration of the slow read; concurrent slow reads tie up further schedulers. The fix waits with Task.yield_many (a non-blocking sweep followed by a blocking wait with timeout: :infinity), so the process sleeps until a task completes instead of spinning.
This issue affects ash: from 2.19.0 before 3.32.2.
