CVE-2015-1530Public exploit

Code execution via unchecked descriptor count multiplication

Published Jan 24, 2020 · Updated Aug 6, 2024

Integer overflow in Google Android before 5.1 allows attackers to execute code with media_server privileges through a crafted application. BnAudioPolicyService::onTransact accepts an unbounded count for QUERY_DEFAULT_PRE_PROCESSING and multiplies it by effect_descriptor_t size, causing the allocation-size product to wrap before descriptor data is written. A malicious application must run on the device; successful exploitation corrupts media_server heap memory, enabling code execution in that service or a crash.
