CVE-2022-50698: ASoC: da7219: Fix an error handling path in da7219_register_dai_clks()

In the Linux kernel, the following vulnerability has been resolved: ASoC: da7219: Fix an error handling path in da7219_register_dai_clks() If clk_hw_register() fails, the corresponding clk should not be unregistered. To handle errors from loops, clean up partial iterations before doing the goto. So add a clk_hw_unregister(). Then use a while (--i >= 0) loop in the unwind section.

Security readout for executives and security teams

Plain-English summary

CVE-2022-50698 is a Linux kernel fix in the DA7219 audio driver. It corrects cleanup logic when clock registration fails. The public record does not provide a CVSS score, business impact, or evidence of active exploitation. Exposure appears limited to systems running affected Linux kernels with this driver path relevant.

Executive priority

Treat as routine kernel maintenance unless your fleet uses affected DA7219 audio paths at scale. There is no cited active exploitation or severity score, but kernel reliability fixes should be incorporated through normal patch cycles after vendor validation.

Technical view

The issue is in ASoC da7219_register_dai_clks(). If clk_hw_register() fails, error handling could unregister the wrong clock state. The fix adds cleanup for partial loop iterations and unwinds previously registered clocks correctly. Public sources identify Linux kernel stable commits but do not describe exploitability or impact beyond the corrected error path.

Likely exposure

Linux systems using affected kernel versions and the DA7219 ASoC audio codec driver may be exposed. Exact exposure depends on kernel branch, backports, hardware, and distribution packaging. The source bundle lists Linux as affected and links stable kernel fixes, but version status should be confirmed with the operating system vendor.

Exploitation context

No active exploitation is cited in the provided sources, and the CVE is not marked as CISA KEV. The available description points to an error-handling flaw during driver clock registration failure, not a documented remote attack path. Practical exploitability is not established in the public record provided.

Researcher notes

Evidence is limited to the CVE record and upstream stable commits. The record does not assign CVSS, CWE, or a clear security impact. Analysis should focus on the DA7219 driver error path and whether downstream kernels backported the unwind fix.

Mitigation direction

  • Apply a vendor-supported Linux kernel update containing the referenced stable fixes.
  • Check distribution security advisories for exact fixed package versions.
  • Prioritize systems with DA7219 audio hardware or enabled ASoC DA7219 support.
  • If no vendor package exists, review upstream stable commits with kernel maintainers.

Validation and detection

  • Inventory Linux kernel versions across affected assets.
  • Confirm whether DA7219 ASoC driver support is present or enabled.
  • Compare deployed kernels with vendor fixed versions or referenced stable commits.
  • Document compensating controls if kernel updates must be deferred.
