What is CVE-2025-71468?

The GPAC media processing framework is susceptible to a NULL pointer dereference vulnerability in the gf_dash_group_get_audio_channels() function. This issue arises from the mishandling of the AudioChannelConfiguration element in the DASH manifest, particularly when crucial attributes such as schemeIdUri or value are omitted. Malicious actors can craft a specific DASH manifest (MPD) that exploits this flaw, leading to application crashes of MP4Box or any GPAC DASH client. This vulnerability poses a significant risk, allowing attackers to disrupt services by causing denial of service conditions.
