In cases where a Catholic is physically or morally impeded from receiving sacramental absolution from a Catholic priest in good standing with faculties, such Catholic may seek the sacrament from a suspended or excommunicated priest, or even priests of those schismatic churches with valid Holy Orders (Eastern Orthodox, Oriental Orthodox, Union of Scranton, some Old Catholic). In such cases the Church supplies what is necessary to validate the sacrament because of the emergency situation (ecclesia supplet). In danger of death, one may even approach a priest whose ordination is doubtfully valid (Novus Ordo, Brasilian Apostolic, some Anglo-Catholics, some sects of the Independent Sacramental Movement*)
*Independent Sacramental Movement (ISM) refers to a diverse body of small ecclesial groups who claim apostolicity through various irregular Old Catholic, Syrian, and Orthodox origins. The ISM covers a very broad spectrum from groups that appear virtually trad Catholic all the way to LGBTXYZ, ancient-alien, neo-Druid, Kabbalistic mystery cults.
