CVE-2026-53152

Kernel crash via missing controller private data

Published Jun 25, 2026 · Updated Jun 25, 2026

NULL-pointer dereference in the Linux kernel Rockchip MMC driver allows affected systems to crash during controller initialization. The dw_mci_rockchip_init function reads host->priv after legacy rk2928, rk3066, and rk3188 controller descriptors failed to allocate that private structure. The fault requires an affected controller and driver revision; the published record identifies no attacker-controlled trigger.
