DescriptionCVE.org

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.

AnalysisAI

Sandbox escape in PipeWire's PulseAudio compatibility layer lets a low-privileged process inside a confined environment such as Flatpak load an attacker-controlled library and execute arbitrary code on the host user's session. The flaw (CWE-427) is present in PipeWire as shipped in Red Hat Enterprise Linux 7, 8, 9 and 10 and carries a scope-changing CVSS 3.1 score of 8.8. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.

Technical ContextAI

PipeWire is the modern Linux multimedia server that handles audio and video routing on most current desktop distributions, and it ships a PulseAudio compatibility layer so legacy PulseAudio clients keep working. The vulnerability is an untrusted-search-path / uncontrolled library-load issue (CWE-427): the PulseAudio compatibility path can be steered into loading a library from an attacker-influenced location. Because Flatpak and similar sandboxes expose the PipeWire/PulseAudio socket into the confined app, a process inside the sandbox that can place or reference a malicious module gets that code executed by PipeWire on the host side, crossing the sandbox trust boundary. The affected components are identified in the input via Red Hat CPEs for red_hat_enterprise_linux 7, 8, 9 and 10.

RemediationAI

No vendor-released patch version is identified in the input at time of analysis; monitor the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-5674 and Bugzilla 2455341 (https://bugzilla.redhat.com/show_bug.cgi?id=2455341) and update the pipewire and pipewire-pulseaudio packages to the fixed build for your RHEL release as soon as it is published, then restart the user session or PipeWire services so the patched code loads. As a compensating control until patched, disable or remove the PulseAudio compatibility layer (the pipewire-pulseaudio / pipewire-pulse component) where legacy PulseAudio clients are not required - this closes the abused code path but breaks audio for applications that still speak the PulseAudio protocol. Additionally, tighten Flatpak permissions so untrusted sandboxed apps do not receive PulseAudio/PipeWire socket access (remove the pulseaudio socket from their permission set), accepting that those apps lose audio, and avoid running untrusted Flatpak applications on affected hosts until the update is applied.
