Description (CNA)
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.
