In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-of-dwcmshc: Prevent illegal clock reduction in HS200/HS400 mode
When operating in HS200 or HS400 timing modes, reducing the clock frequency below 52MHz will lead to link broken as the Rockchip DWC MSHC controller requires maintaining a minimum clock of 52MHz in these modes.
Add a check to prevent illegal clock reduction through debugfs:
