A fix is available and has been applied in the Linux kernel after version 5.7, as indicated by the listed fixed commit hashes. Users and administrators should update their Linux kernel to a version including these fixes to remediate the vulnerability.

Description

CVE-2026-80526 is a high-severity vulnerability in the Linux kernel's ASoC driver for the tas2562 audio codec. The vulnerability arises because the tas2562_volume_control_put() function does not validate user-supplied control values before using them as an index into a fixed-size array, leading to a potential buffer overflow. This flaw has been fixed by adding proper validation to ensure only valid array indices are used.
