CVE-2025-24132 is a vulnerability identified in Apple's AirPlay audio SDK, specifically related to improper memory handling that can be triggered by an attacker on the local network. The flaw allows an unauthenticated attacker with network access to cause an unexpected application termination, effectively a denial-of-service (DoS) condition. The vulnerability is classified under CWE-119, which pertains to improper restriction of operations within the bounds of a memory buffer, indicating a memory corruption issue. The problem affects versions prior to the patched releases: AirPlay audio SDK 2.7.1, AirPlay video SDK 3.6.0.126, and CarPlay Communication Plug-in R18.1. Exploitation requires no user interaction and no privileges, but the attacker must be on the same local network segment as the target device to send crafted network packets that trigger the memory handling flaw. The CVSS v3.1 base score is 6.5 (medium severity), reflecting the vulnerability's impact on availability only, with no impact on confidentiality or integrity. There are no known exploits in the wild at the time of publication. This vulnerability could disrupt the normal operation of applications relying on the AirPlay audio SDK, causing them to crash unexpectedly, potentially impacting user experience and service availability in environments where AirPlay streaming is critical.

For European organizations, the primary impact of CVE-2025-24132 lies in service disruption rather than data compromise. Enterprises and public sector entities that utilize Apple AirPlay technology for audio streaming in conference rooms, public announcement systems, or multimedia presentations may experience unexpected application crashes, leading to interruptions in communication and collaboration workflows. This could be particularly problematic in sectors such as education, healthcare, and corporate environments where reliable audio streaming is essential. While the vulnerability does not allow data theft or system takeover, repeated exploitation could degrade trust in the affected services and require operational overhead to manage. Additionally, organizations with extensive use of CarPlay-enabled vehicles or integrated Apple multimedia systems could face disruptions in vehicle infotainment or communication systems, potentially impacting fleet operations or user satisfaction. The requirement for local network access limits the attack surface to internal networks, but in environments with weak network segmentation or guest network access, the risk of exploitation increases. Overall, the impact is availability-focused and could affect business continuity and user experience in environments heavily dependent on Apple AirPlay audio streaming technologies.

To mitigate CVE-2025-24132 effectively, European organizations should prioritize updating all affected Apple AirPlay audio SDK components to the fixed versions: AirPlay audio SDK 2.7.1, AirPlay video SDK 3.6.0.126, and CarPlay Communication Plug-in R18.1. Beyond patching, network segmentation should be enforced to isolate devices running AirPlay services from untrusted or guest network segments, reducing the risk of local network attackers reaching vulnerable devices. Implementing strict access controls on local networks, including 802.1X authentication and network access control (NAC) solutions, can further limit unauthorized devices from connecting. Monitoring network traffic for unusual or malformed AirPlay protocol packets may help detect attempted exploitation attempts. Organizations should also review and restrict multicast and broadcast traffic where possible, as AirPlay relies on these for device discovery and communication. For environments using CarPlay, ensure that vehicle infotainment systems are updated and that physical access to vehicles is controlled to prevent local network attacks. Finally, educating IT staff and end-users about the importance of applying updates promptly and maintaining secure local network practices will enhance overall resilience against this vulnerability.
