Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Original source description

Read the full publisher description

In the Linux kernel, the following vulnerability has been resolved:

mmc: sdhci-sprd: disable runtime PM on remove

sdhci_sprd_probe() enables runtime PM, while sdhci_sprd_remove() does not perform the corresponding runtime PM cleanup.

The probe failure path disables runtime PM before disabling the clocks, but the normal remove path directly disables clocks that are also managed by the runtime PM callbacks. If the device is runtime suspended, those clocks may already be disabled.

Resume the device before removal, disable runtime PM and drop the temporary runtime PM reference before disabling the clocks.

This issue was found by manual code inspection.
