Description OSIDB Bzimport 2026-10-23 13:50:43 UTC
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.
