What happened
The Dolby codec Android vulnerability exposes devices to remote code execution through malformed audio files. Security analysts at Trend Micro discovered that the flaw exists in Dolby Digital Plus implementations on Android devices running versions 11 through 14. Malformed MP4 or AAC files could trigger a buffer overflow, allowing attackers to execute arbitrary code. Attackers could deliver payloads via malicious apps, messaging, or compromised media websites. Exploitation requires user interaction, such as opening a crafted media file, but no privilege escalation is needed. The flaw affects multiple Android OEMs, including Samsung, Xiaomi, and OnePlus, as they integrate Dolby codecs into system media frameworks.
Who is affected
Android device users and mobile app ecosystems are at risk, with exposure being direct on vulnerable devices and potentially indirect if malware spreads through apps or messaging platforms.
Why CISOs should care
Unpatched codec vulnerabilities enable malware deployment, lateral movement, and potential persistence in enterprise-managed Android devices, impacting mobile security and user data integrity.
3 practical actions
Apply vendor patches: Update all affected Android devices and media frameworks immediately.
Limit file handling: Restrict unknown media file downloads and scanning for malicious formats.
Monitor mobile endpoints: Detect abnormal app behavior and audio-processing exceptions to catch potential exploitation.
