In the Linux kernel, the following vulnerability has been resolved: nvme-pci: add missing condition check for existence of mapped data nvme_map_data() is called when request has physical segments, hence the nvme_unmap_data() should have same condition to avoid dereference.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nvme-pci: agrega condición faltante para verificar la existencia de datos mapeados. Se llama a nvme_map_data() cuando la solicitud tiene segmentos físicos, por lo tanto, nvme_unmap_data() debe tener la misma condición para evitar la desreferencia.
