In the Linux kernel, the following vulnerability has been resolved:

net: bcmgenet: fix off-by-one in bcmgenet_put_txcb

The write_ptr points to the next open tx_cb. We want to return the tx_cb that gets rewinded, so we must rewind the pointer first then return the tx_cb that it points to. That way the txcb can be correctly cleaned up.
