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.
