AI-suggested
A patch is available for this vulnerability. Users should apply the official Linux kernel updates that include the fix for CVE-2026-74332. The vendor advisory confirms the issue is resolved in updated kernel versions. No additional mitigation actions are specified or required beyond applying the patch.
Description
A vulnerability in the Linux kernel's ASoC AMD ACP-SDW-SOF driver was resolved. The issue involved an out-of-bounds read in the create_sdw_dailinks() function due to improper iteration over the sof_dais array when all entries were initialized. This could lead to reading past the end of the array. The flaw has been fixed by passing the allocated entry count to prevent out-of-bounds access. The vulnerability affects specific Linux kernel versions and has a CVSS score of 8.4. A patch is available to address this issue.
