Description OSIDB Bzimport 2026-07-01 12:33:06 UTC 
A flaw was found in PipeWire's PulseAudio protocol server. Multiple
  functions use alloca() without bounds checking to allocate arrays
  based on counts from card parameters or client properties. A
  malicious PulseAudio client can trigger stack exhaustion by sending
  requests with very large parameter counts, crashing the PipeWire
  daemon.
