  3. CVE-2024-57911
In the Linux kernel, the following vulnerability has been resolved: iio: dummy: iio_simply_dummy_buffer: fix information leak in triggered buffer The 'data' array is allocated via kmalloc() and it is used to push data to user space from a triggered buffer, but it does not set values for inactive channels, as it only uses iio_for_each_active_channel() to assign new values. Use kzalloc for the memory allocation to avoid pushing uninitialized information to userspace.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: iio: dummy: iio_simply_dummy_buffer: corrige la fuga de información en el búfer activado La matriz 'data' se asigna a través de kmalloc() y se utiliza para enviar datos al espacio del usuario desde un búfer activado, pero no establece valores para canales inactivos, ya que solo utiliza iio_for_each_active_channel() para asignar nuevos valores. Utilice kzalloc para la asignación de memoria para evitar enviar información no inicializada al espacio del usuario.
