CVE-2024-46862: ASoC: Intel: soc-acpi-intel-mtl-match: add missing empty item

In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: soc-acpi-intel-mtl-match: add missing empty item There is no links_num in struct snd_soc_acpi_mach {}, and we test !link->num_adr as a condition to end the loop in hda_sdw_machine_select(). So an empty item in struct snd_soc_acpi_link_adr array is required.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel defect in Intel audio platform matching logic. A required empty terminator entry was missing, so kernel code that scans the table may not know where to stop. The public bundle does not provide impact details, CVSS, or evidence of real-world exploitation.

Executive priority

Treat as a low-visibility kernel maintenance item until vendor guidance provides impact detail. It does not currently justify emergency response based on the supplied evidence, but affected Linux fleets should receive normal kernel updates.

Technical view

The issue is in ASoC Intel soc-acpi-intel-mtl-match. hda_sdw_machine_select() ends iteration by testing !link->num_adr because struct snd_soc_acpi_mach has no links_num. The fix adds the missing empty snd_soc_acpi_link_adr array item used as the loop terminator.

Likely exposure

Exposure appears limited to affected Linux kernels using this Intel ASoC ACPI matching path. The bundle lists Linux kernel versions including 6.10, 6.10.11, and 6.11, plus commit f77ae7fcdc47630eb7653983f3c57ac44103aebc. Downstream distribution impact depends on vendor kernel backports.

Exploitation context

CISA KEV status is false in the bundle, and no cited source states active exploitation. The public record does not describe a practical attack path, required privileges, crash behavior, or confidentiality/integrity impact.

Researcher notes

Key uncertainty is impact. The source describes an unterminated array used by machine-selection logic, but not the failure mode. Validate by source or vendor patch presence, not by attempting exploit reproduction.

Mitigation direction

  • Check your Linux vendor advisory for CVE-2024-46862 applicability.
  • Update affected kernels to vendor packages containing the referenced stable fixes.
  • Prioritize systems using Intel ASoC or SoundWire audio on affected kernel lines.
  • Track downstream backports rather than relying only on upstream version numbers.

Validation and detection

  • Inventory Linux kernel versions across endpoints and appliances.
  • Identify systems running affected 6.10 or 6.11 kernel lines from the bundle.
  • Check vendor changelogs for the referenced stable commit IDs.
  • Confirm patched systems no longer map to affected vendor kernel builds.
