CVE-2015-3864

CWE-189Published: October 1, 2015· Updated: Jun 17, 2026

10.0

CVSS v3.1

Official Description

Integer underflow in the MPEG4Extractor::parseChunk function in MPEG4Extractor.cpp in libstagefright in mediaserver in Android before 5.1.1 LMY48M allows remote attackers to execute arbitrary code via crafted MPEG-4 data, aka internal bug 23034759. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-3824.

Technical Analysis

CVE-2015-3864 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2015-3864. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
