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.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2029 advisory.

    RAOP module accepts unbounded Content-Length values and does not check the pw_array_add() return.
    (CVE-2026-14324)

    Multiple unbounded alloca() calls in the PulseAudio protocol server. (CVE-2026-14330)
