"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnvme-pci: fix dma mapping leak on data setup error\n\nWe're leaking the initial DMA mapping during iteration if we fail to\nallocate the tracking descriptor for both PRP and SGL. Unmap the\niterator directly; we can't use the existing unmap helper because it\ndepends on the tracking descriptor being successfully allocated, so a\nnew one for an in-use iterator is provided.\n\nThe mappings were also leaking when the driver detects an invalid\nbio_vec when mapping PRPs, so fix that too."
