CVE-2025-38648

  3. CVE-2025-38648
In the Linux kernel, the following vulnerability has been resolved: spi: stm32: Check for cfg availability in stm32_spi_probe The stm32_spi_probe function now includes a check to ensure that the pointer returned by of_device_get_match_data is not NULL before accessing its members. This resolves a warning where a potential NULL pointer dereference could occur when accessing cfg->has_device_mode. Before accessing the 'has_device_mode' member, we verify that 'cfg' is not NULL. If 'cfg' is NULL, an error message is logged. This change ensures that the driver does not attempt to access configuration data if it is not available, thus preventing a potential system crash due to a NULL pointer dereference.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: spi: stm32: Comprobar la disponibilidad de cfg en stm32_spi_probe La función stm32_spi_probe ahora incluye una comprobación para garantizar que el puntero devuelto por of_device_get_match_data no sea NULL antes de acceder a sus miembros. Esto resuelve una advertencia donde podría ocurrir una posible desreferencia de puntero NULL al acceder a cfg->has_device_mode. Antes de acceder al miembro 'has_device_mode', verificamos que 'cfg' no sea NULL. Si 'cfg' es NULL, se registra un mensaje de error. Este cambio garantiza que el controlador no intente acceder a los datos de configuración si no están disponibles, previniendo así un posible fallo del sistema debido a una desreferencia de puntero NULL.
