In the Linux kernel, the following vulnerability has been resolved:

nvme-pci: fix dma mapping leak on data setup error

We're leaking the initial DMA mapping during iteration if we fail to allocate the tracking descriptor for both PRP and SGL. Unmap the iterator directly; we can't use the existing unmap helper because it depends on the tracking descriptor being successfully allocated, so a new one for an in-use iterator is provided.

The mappings were also leaking when the driver detects an invalid bio_vec when mapping PRPs, so fix that too.
