"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ne1000/e1000e: Fix leak in 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 after a successful 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 would leak.\n\nIn these commits, a faulty while condition caused an infinite loop in\ndma_error:\nCommit 03b1320dfcee (\"e1000e: remove use of skb_dma_map from e1000e\ndriver\")\nCommit 602c0554d7b0 (\"e1000: remove use of skb_dma_map from e1000 driver\")\n\nCommit c1fa347f20f1 (\"e1000/e1000e/igb/igbvf/ixgb/ixgbe: Fix tests of\nunsigned in *_tx_map()\") fixed the infinite loop, but introduced the\noff-by-one error.\n\nThis issue may still exist in the igbvf driver, but I did not address it\nin this patch."
