Therefore there is a race window\nbetween dasd_alias_get_start_dev() and _lcu_update() which sets\npavgroup to NULL with the lcu->lock held.\n\nFix by checking the pavgroup pointer with lcu->lock held."

"value": "En el kernel de Linux, se resolvi\u00f3 la siguiente vulnerabilidad: s390/dasd: corrige Ups en dasd_alias_get_start_dev debido a la falta de pavgroup. Corrige Ups en la funci\u00f3n dasd_alias_get_start_dev() causada porque el puntero pavgroup es NULL. El puntero pavgroup se verifica en la entrada de la funci\u00f3n pero sin que se mantenga presionado el bloqueo lcu->. Por lo tanto, existe una ventana de ejecuci\u00f3n entre dasd_alias_get_start_dev() y _lcu_update() que establece pavgroup en NULL con el bloqueo lcu->retenido. Para solucionarlo, compruebe el puntero de pavgroup con lcu->lock retenido."
