CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.6.152/6.12.104/6.18.45/7.1.9 and classified as very critical. This issue affects the function tas2562_volume_control_put of the component tas2562. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2026-80526 since 08/26/2026. The exploitation is known to be easy. An attack has to be approached locally. The exploitation requires an enhanced level of successful authentication. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/26/2026).

Upgrading to version 6.6.153, 6.12.105, 6.18.46 or 7.1.10 eliminates this vulnerability. Applying the patch 1f389ecd0c35e9e281036e44c121df904f3164c1/20bdbb1376457ecbf418bf677fd285820d1fc011/db488d653d896fcf9ac87e15239924c2928bbc3c/c37a0461c0d0a70c5de4fdbd70449a7f53c12dda/8fb41964f7e4e4207c8999af2056894caa7a252a is able to eliminate this problem.
