CVE-2025-48592Network attack vector

Remote information disclosure via multilayer AV1 decoding

Published Dec 8, 2025 · Updated Dec 17, 2025

Out-of-bounds read in Google Cloud Android 15 and 16 allows remote attackers to disclose heap data through crafted scalable AV1 video. C2SoftDav1dDec's initDecoder retains dav1d's all-layers default even though the wrapper cannot handle every scalable-video layer buffer. No privileges or user interaction are required, and the documented consequence is limited to information disclosure.
