CVE-2026-53152

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).

Understanding the Weakness (CWE)

Availability

Technical Impact: DoS: Crash, Exit, or Restart

NULL pointer dereferences usually result in the failure of the process unless exception handling (on some platforms) is available and implemented. Even when exception handling is being used, it can still be very difficult to return the software to a safe state of operation.

Integrity,Confidentiality

Technical Impact: Execute Unauthorized Code or Commands; Read Memory; Modify Memory

In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution.
