In the Linux kernel, the following vulnerability has been resolved:
net: macb: fix dma_alloc_coherent() leak on macb_alloc() error paths
Fix 3 leaks in macb_alloc() error paths:
This is because our error handling calls macb_free(bp) which in turn frees the buffers stored in bp->queues[0], but nothing has been stored in there. Fix by storing allocated buffers into bp->queues[0] ASAP.
