Description

A flaw was found in the Linux kernel's dw_mmc-rockchip driver. This vulnerability occurs because older controllers (such as rk2928, rk3066, and rk3188) lack necessary private data. When the system attempts to access this missing data, it results in a NULL-pointer dereference. This can lead to system instability or a denial of service (DoS).

Mitigation

No mitigation is specified in collected source.
