CVE-2026-74332 Linux CVE debrief

A Linux kernel vulnerability has been identified in ASoC: amd: acp-sdw-sof, which could allow for out-of-bounds memory access. The issue arises from the create_sdw_dailinks function, which does not properly bound the iteration over the sof_dais array. This could potentially lead to a denial of service or code execution. The vulnerability affects Linux kernel developers and maintainers, Linux distribution maintainers, and users of Linux-based systems. The CVE record and source item provide details on the vulnerability, including its description and affected versions.

Who should care

Linux kernel developers and maintainers, Linux distribution maintainers, and users of Linux-based systems should assess exposure and apply patches. The vulnerability affects those who use Linux-based systems and requires verification of system exposure and patch application.

Why it matters

This vulnerability in the Linux kernel could allow for denial of service or code execution due to out-of-bounds memory access. Linux kernel developers and maintainers, Linux distribution maintainers, and users of Linux-based systems should assess exposure and apply patches.

  • Denial of service due to out-of-bounds memory access
  • Potential code execution due to lack of bounds checking
  • Verification of system exposure and patch application required
  • Monitoring system logs for potential exploitation attempts necessary

Technical summary

The create_sdw_dailinks function in ASoC: amd: acp-sdw-sof does not properly bound the iteration over the sof_dais array, potentially leading to out-of-bounds memory access. This vulnerability could allow for denial of service or code execution due to out-of-bounds memory access. Linux kernel developers and maintainers, Linux distribution maintainers, and users of Linux-based systems should assess exposure and apply patches. The official CVE Program record and NIST NVD detail page provide additional information on the vulnerability.

Defensive priority

High

Recommended defensive actions

  • Review and apply patches from the Linux kernel maintainers
  • Verify system exposure and update vulnerable systems
  • Monitor system logs for potential exploitation attempts
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and source item provide details on the vulnerability, including its description and affected versions. However, the corpus does not establish versions, exploitation, impact, or remediation, which require verification from the supplied official sources. The official CVE Program record and NIST NVD detail page provide additional information on the vulnerability.
