CVE-2026-80526 Linux CVE debrief

Who should care

Linux system administrators, kernel maintainers, and developers working with the ASoC tas2562 component should assess exposure and apply patches or compensating controls as necessary.

Why it matters

CVE-2026-80526 is a high-severity vulnerability in the Linux kernel's ASoC tas2562 component, allowing for out-of-bounds writes due to lack of input validation. Linux system administrators and developers should assess exposure, apply patches, and monitor systems for potential security issues.

• Potential for arbitrary value writes to the device, which could lead to system instability or security issues.
• Exposure of Linux systems using affected kernel versions, requiring inventory checks and potential patching.
• Need for monitoring system logs to detect unusual activity related to the ASoC tas2562 component.
• Verification of patch application and system hardening to prevent exploitation.

Technical summary

The Linux kernel's ASoC tas2562 component is vulnerable to an out-of-bounds write due to improper validation of user-supplied volume control values. This can lead to an overflow and arbitrary value write to the device. The issue has been addressed by adding validation for control values. Affected Linux system administrators and developers should assess exposure, apply patches, and monitor systems for potential security issues related to the ASoC tas2562 component. The vulnerability has a high severity with a CVSS score of 7.8, emphasizing the need for prompt action.

Defensive priority

Medium

Recommended defensive actions
