Description

A flaw was found in the Linux kernel's Spreadtrum SDHCI (Secure Digital Host Controller Interface) driver. This flaw allows a local privileged user to cause a Denial of Service (DoS) by triggering improper power management cleanup during device removal. Because the driver fails to disable runtime power management before disabling hardware clocks, unbinding or removing a suspended device can lead to state inconsistencies and a system crash.
