CVE-2024-36029: mmc: sdhci-msm: pervent access to suspended controller

In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-msm: pervent access to suspended controller Generic sdhci code registers LED device and uses host->runtime_suspended flag to protect access to it. The sdhci-msm driver doesn't set this flag, which causes a crash when LED is accessed while controller is runtime suspended. Fix this by setting the flag correctly.

Security readout for executives and security teams

Plain-English summary

This Linux kernel issue can crash affected systems when an SDHCI MSM storage controller is suspended and an LED path accesses it. The public record describes availability impact, not data theft or privilege escalation. Severity is not scored in the provided sources.

Executive priority

Treat this as a targeted platform reliability issue until more severity data is available. Prioritize patch validation for Qualcomm-based Linux devices where storage-controller crashes could disrupt operations or embedded services.

Technical view

The sdhci-msm MMC driver failed to set host->runtime_suspended. Generic SDHCI LED handling relies on that flag to avoid touching a runtime-suspended controller. The resolved fix sets the flag correctly to prevent crashes during suspended-controller LED access.

Likely exposure

Exposure appears limited to Linux systems using the Qualcomm MSM SDHCI/MMC driver on affected kernel versions or unpatched downstream kernels. The source lists affected Linux versions through 6.9 and stable commit references, but no CPEs.

Exploitation context

The source bundle does not show active exploitation, and KEV is false. The described trigger is LED access while the controller is runtime suspended. The attacker model and remote reachability are not defined in the supplied sources.

Researcher notes

Evidence is limited to the kernel CVE record and stable fixes. No CVSS, CWE, exploit status, or precise affected distribution package list is provided. Avoid assuming broader Linux exposure without confirming sdhci-msm hardware and driver use.

Mitigation direction

  • Update to a kernel containing the referenced stable fix commits.
  • Check Linux distribution advisories for backported fixes to packaged kernels.
  • Prioritize Qualcomm MSM platforms using the sdhci-msm MMC driver.
  • If updates are unavailable, follow vendor guidance for temporary operational workarounds.

Validation and detection

  • Inventory Linux kernel versions on Qualcomm MSM-based systems.
  • Confirm whether the sdhci-msm driver is present and used.
  • Verify the relevant stable fix is included or backported.
  • Review crash logs for SDHCI, MMC, LED, or runtime power-management faults.
