DescriptionCVE.org

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

AnalysisAI

Denial-of-service via NULL pointer dereference in PipeWire's RAOP (Remote Audio Output Protocol) module affects Red Hat Enterprise Linux 8, 9, and 10. The RAOP module fails to enforce an upper bound on Content-Length values in incoming requests and does not validate the return value of pw_array_add(); when a sufficiently large Content-Length triggers an allocation failure, the unchecked NULL return causes a crash of the PipeWire daemon, resulting in complete loss of audio services. No special authentication is required from the adjacent network, and no public exploit or CISA KEV listing has been identified at time of analysis.

Technical ContextAI

PipeWire is the modern multimedia server framework replacing PulseAudio and JACK in mainstream Linux distributions, including RHEL 8/9/10. Its RAOP module implements the Remote Audio Output Protocol (Apple's proprietary AirPlay-style streaming protocol) over RTSP, allowing PipeWire to act as an AirPlay sink. The function pw_array_add() is a PipeWire internal API that appends to a dynamic array and returns NULL on allocation failure. CWE-476 (NULL Pointer Dereference) captures the root cause: the caller in the RAOP module does not inspect the return value of pw_array_add() before dereferencing it. Separately, the absence of an upper-bound check on Content-Length enables an attacker to supply an arbitrarily large value, which can exhaust memory or directly trigger the allocation failure path, making the NULL dereference reliably reachable. Affected CPEs are cpe:2.3:a:red_hat:red_hat_enterprise_linux_8/9/10.

RemediationAI

The primary remediation is to apply the vendor-supplied package update for PipeWire once Red Hat publishes a patched RPM via RHSA; monitor https://access.redhat.com/security/cve/CVE-2026-14324 for patch availability and apply through standard yum/dnf update channels. No exact patched version number is confirmed in the available data - do not assume a fix is available until the Red Hat advisory specifies an updated package version. As a compensating control, disable or mask the PipeWire RAOP module on hosts where AirPlay sink functionality is not required (e.g., remove or comment out the module-raop-sink configuration in the PipeWire session config directory under /etc/pipewire/ or ~/.config/pipewire/); this eliminates the attack surface entirely at the cost of losing AirPlay audio streaming capability. Additionally, network segmentation restricting adjacency - placing workstations behind VLANs that prevent arbitrary hosts from reaching the RAOP RTSP port - limits exposure to trusted network segments. Note that masking the module may affect accessibility or media workflows that depend on AirPlay output.
