Out-of-Bounds Write Vulnerability in Dolby UDC Software
CVE-2025-54957
What is CVE-2025-54957?
CVE-2025-54957 is a significant vulnerability identified in the Dolby UDC software, specifically affecting versions 4.5 through 4.13. Dolby UDC is designed for audio processing, particularly in handling the Dolby Digital Plus (DD+) format, which is widely used in various media applications. The vulnerability stems from an out-of-bounds write issue that occurs when a malformed DD+ bitstream is processed. This issue results from an integer wraparound in the length calculation for a write operation, which can lead to a buffer overflow. Consequently, the decoder may crash, resulting in potential service disruptions or degradation in media playback performance, affecting user experiences and operational functionalities.
Potential impact of CVE-2025-54957
-
Service Disruption: The immediate effect of this vulnerability is the potential for crashes in the DD+ decoder process, which can interrupt media playback and impact user access to audio content, leading to a degraded user experience.
-
Security Risks: The out-of-bounds write could potentially be exploited by malicious actors to corrupt memory or execute arbitrary code, placing systems at risk of unauthorized access and compromise.
-
Reputation Damage: Organizations relying on Dolby UDC for their audio processing needs may face reputational harm if they fail to address this vulnerability, particularly if it leads to service outages or data integrity issues, undermining user trust and confidence.
