Description
A flaw was found in the Linux kernel's nvme-pci driver. This vulnerability occurs when descriptor Direct Memory Access (DMA) pools are created during device probing but are not properly released if the probe operation fails. This oversight leads to a memory leak, where dma_pool objects are not freed, potentially causing resource exhaustion and a Denial of Service (DoS) over time.
