CVE-2024-36890

In the Linux kernel, the following vulnerability has been resolved: mm/slab: make __free(kfree) accept error pointers Currently, if an automatically freed allocation is an error pointer that will lead to a crash. An example of this is in wm831x_gpio_dbg_show(). 171 char *label __free(kfree) = gpiochip_dup_line_label(chip, i); 172 if (IS_ERR(label)) { 173 dev_err(wm831x->dev, "Failed to duplicate label\n"); 174 continue; 175 } The auto clean up function should check for error pointers as well, otherwise we're going to keep hitting issues like this.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mm/slab: make __free(kfree) acepta punteros de error Actualmente, si una asignación liberada automáticamente es un puntero de error que provocará un bloqueo. Un ejemplo de esto está en wm831x_gpio_dbg_show(). 171 caracteres *etiqueta __free(kfree) = gpiochip_dup_line_label(chip, i); 172 if (IS_ERR(etiqueta)) { 173 dev_err(wm831x->dev, "Error al duplicar la etiqueta\n"); 174 continúan; 175 } La función de limpieza automática también debería comprobar si hay indicadores de error; de lo contrario, seguiremos teniendo problemas como este.
