CVE-2026-98412
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:
power: sequencing: corrige una desreferencia de puntero NULL en pwrseq_unit_new()
Si falla la asignación de memoria en pwrseq_unit_setup_deps(), se llama a pwrseq_unit_put() para liberar la unidad parcialmente inicializada. Sin embargo, nunca hemos inicializado unit->list y pwrseq_unit_release() llamará incondicionalmente a list_del() sobre ella. Inicialice unit->list justo después de asignar la estructura de la unidad.
