CVE-2026-80526— ASoC: tas2562: Validate values for volume writes

Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux 内核中的以下漏洞已修复： ASoC: tas2562: 对音量写入的值进行校验 函数没有对用户空间写入的控制值进行任何校验，而是直接使用该值作为索引，在一个固定大小的数组中查找对应值。该数组很容易发生越界访问，随后将查到的值直接写入设备。本次修复增加了校验逻辑，确保只加载数组中实际存在的值。

Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: tas2562: Validate values for volume writes tas2562_volume_control_put() does not do any validation of the control value written by userspace, it uses it to look up a value in a fixed size array which can easily be overflowed and then writes whatever value it gets back to the device. Add validation that we are loading a value we have in the array.
