      "title": "igbvf: Fix leak in TX DMA error cleanup",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nigbvf: Fix leak in TX DMA error cleanup\n\nIf an error is encountered while mapping TX buffers, the driver should\nunmap any buffers already mapped for that skb.\n\nBecause count is incremented before each frag mapping, it will always\nmatch the correct number of unmappings needed when dma_error is reached.\nDecrementing count before the while loop in dma_error causes an\noff-by-one error. If any mapping was successful before an unsuccessful\nmapping, exactly one DMA mapping (the head) would leak.\n\nThis bug was introduced by a 2010 fix for an endless loop in dma_error.\nAll other affected drivers have already been fixed.",
