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:
- Tx buffer allocated but crossing a 4G boundary: Tx leaked.
- Rx buffer allocation fails: Tx leaked.
- Rx buffer allocated but crossing a 4G boundary: Tx & Rx leaked.
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.
