"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: macb: fix dma_alloc_coherent() leak on macb_alloc() error paths\n\nFix 3 leaks in macb_alloc() error paths:\n- Tx buffer allocated but crossing a 4G boundary: Tx leaked.\n- Rx buffer allocation fails: Tx leaked.\n- Rx buffer allocated but crossing a 4G boundary: Tx & Rx leaked.\n\nThis is because our error handling calls macb_free(bp) which in turn\nfrees the buffers stored in bp->queues[0], but nothing has been stored\nin there. Fix by storing allocated buffers into bp->queues[0] ASAP."
