CVE-2021-0379Network attack vector

Remote information disclosure via unchecked MP3 bitstream read

Published Mar 10, 2021 · Updated Aug 3, 2024

Out-of-bounds read in the Android 11 Media framework allows remote attackers to disclose process memory through a crafted MP3 file. The getUpTo17bits function in pvmp3_getbits.cpp reads bitstream bytes without first confirming that the required bytes remain in the input buffer. Exploitation requires a user to process the crafted media; no additional execution privileges are required, and the reported consequence is memory disclosure only.
