CVE-2026-5674

Pipewire: pipewire: sandbox escape and arbitrary code execution via malicious library loading

publishedCWE-427

A flaw was found in PipeWire, a multimedia server. This vulnerability allows an attacker to escape sandboxed applications, such as Flatpak, by exploiting PipeWire's PulseAudio compatibility layer. An attacker with minimal permissions within a sandboxed environment can load a malicious library, leading to arbitrary code execution outside the sandbox and potential compromise of the user's system.

Fixes and workarounds

Workaround

To mitigate this issue, restrict containerized applications from accessing the PulseAudio socket or writing to host-visible paths. Additionally, configure PipeWire to prevent module loading by setting `pulse.allow-module-loading = false` in the PipeWire PulseAudio configuration. Alternatively, restrict the `dlopen()` paths for `module-ladspa-sink` to trusted system directories like `/usr/lib/ladspa/` and `/usr/lib64/ladspa/`. Applying these changes may require restarting the PipeWire service to take effect, which could impact audio functionality.
