Be Careful with Audio on Your Device: A Vulnerability in Audio Could Allow Hackers Access

CVSScvssV3_1: 8.4

There is a vulnerability that has been discovered in how some devices handle audio playback and recording. The vulnerability, tracked as CVE-2023-21672, has a CVSS score of 8.4 out of 10, meaning it is considered highly severe.

This issue affects the way audio “tunnels” are managed when playing back or recording audio concurrently. A hacker could potentially exploit memory corruption happening in the audio subsystem. This could allow them to execute arbitrary code or escalate their privileges.

If exploited, a hacker may be able to install programs, view, change or delete data, or create new accounts with full user rights on affected devices. As audio playback and recording are common activities, this makes for a serious security risk.

The best way to protect yourself is to keep your operating system and apps up-to-date with the latest software patches, as updates may have already addressed this vulnerability. You should also be cautious about opening unknown files or installing apps from untrusted third-party sources, as those are common ways for hackers to gain access to devices.

Staying on top of software updates and practicing basic cyber safety habits can go a long way in protecting you from audio-related vulnerabilities like this one. Let’s all do our part to help secure our devices.
