CVE-2025-36924

Adjacent privilege escalation via modem buffer overwrite

Published Dec 11, 2025 · Updated Dec 11, 2025

Out-of-bounds write in Android on supported Pixel devices allows remote authenticated users to escalate privileges through adjacent access. ss_DecodeLcsAssistDataReqMsg in ss_LcsManagement.c applies an incorrect bounds check while decoding LCS assistance data, allowing a write past the destination buffer. Low privileges are required to reach the modem path, and successful exploitation can compromise device data and operation without user interaction.
