      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\npadata: use integer wrap around to prevent deadlock on seq_nr overflow\n\nWhen submitting more than 2^32 padata objects to padata_do_serial, the\ncurrent sorting implementation incorrectly sorts padata objects with\noverflowed seq_nr, causing them to be placed before existing objects in\nthe reorder list. This leads to a deadlock in the serialization process\nas padata_find_next cannot match padata->seq_nr and pd->processed\nbecause the padata instance with overflowed seq_nr will be selected\nnext.\n\nTo fix this, we use an unsigned integer wrap around to correctly sort\npadata objects in scenarios with integer overflow."

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: padata: usar un envoltorio de enteros para evitar un bloqueo en el desbordamiento de seq_nr Al enviar m\u00e1s de 2^32 objetos padata a padata_do_serial, la implementaci\u00f3n de clasificaci\u00f3n actual ordena incorrectamente los objetos padata con seq_nr desbordado, lo que hace que se coloquen antes de los objetos existentes en la lista de reordenamiento. Esto conduce a un bloqueo en el proceso de serializaci\u00f3n ya que padata_find_next no puede coincidir con padata->seq_nr y pd->processed porque la instancia de padata con seq_nr desbordado se seleccionar\u00e1 a continuaci\u00f3n. Para solucionar esto, usamos un envoltorio de enteros sin signo para ordenar correctamente los objetos padata en escenarios con desbordamiento de enteros."
