Out-of-Bounds Read Vulnerability in Samsung's Audio Processing Library

CVE-2025-20944

What is CVE-2025-20944?

CVE-2025-20944 is an out-of-bounds read vulnerability found in Samsung's audio processing library, specifically within the file libsavsac.so. This library plays a crucial role in managing audio data processing for various Samsung products. The vulnerability could allow local attackers to manipulate the library to read memory beyond the intended limits, potentially exposing sensitive information or system data. Given the widespread use of Samsung's audio processing capabilities across a range of devices, organizations relying on Samsung technology could face significant risks if this vulnerability is not addressed.

Technical Details

This vulnerability occurs during the parsing of audio data in libsavsac.so. The flaw enables an out-of-bounds read, which means that attackers can access memory locations that should not be readable, allowing them to bypass safeguards that typically protect sensitive information. The vulnerability affects versions of the library prior to the SMR Apr-2025 Release 1. Being a local vulnerability, exploitation requires access to the system, but it still poses a risk to data integrity and confidentiality.

Potential Impact of CVE-2025-20944

1. Data Exposure: The out-of-bounds read can lead to unauthorized access to sensitive information held in memory, which may include user data or application secrets.

2. System Integrity Compromise: Attackers exploiting this vulnerability may gain insights into the internal workings of the audio processing library, potentially leading to further vulnerabilities or system compromises.

3. Increased Attack Surface: The existence of this flaw could encourage attackers to develop more sophisticated methods for further intrusion, thus increasing the overall risk to systems using Samsung’s audio technologies.
