CVE-2026-53152

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mmc: dw_mmc-rockchip: Add missing private data for very old controllers<br /> <br /> The really old controllers (rk2928, rk3066, rk3188) do not support UHS<br /> speeds at all, and thus never handled phase data.<br /> <br /> For that reason it never had a parse_dt callback and no driver private<br /> data at all.<br /> <br /> Commit ff6f0286c896 ("mmc: dw_mmc-rockchip: Add memory clock auto-gating<br /> support") makes the private data sort of mandatory, because the init<br /> function checks whether phases are configured internally or through the<br /> clock controller.<br /> <br /> This results in the old SoCs then experiencing NULL-pointer dereferences<br /> when they try to access that private-data struct.<br /> <br /> While we could have if (priv) conditionals in all places, it&amp;#39;s way less<br /> cluttery to just give the old types their private-data struct.
