What is CVE-2026-5674?

A security flaw in PipeWire, a multimedia server used for handling audio and video streams, enables attackers to escape sandboxed environments such as Flatpak. The vulnerability arises from PipeWire's compatibility with PulseAudio, allowing an attacker with limited permissions to load malicious libraries. This capability can lead to arbitrary code execution beyond the confines of the sandbox, posing a serious risk of system compromise for users.
