Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: bcmgenet: fix off-by-one in bcmgenet_put_txcb<br /> <br /> The write_ptr points to the next open tx_cb. We want to return the<br /> tx_cb that gets rewinded, so we must rewind the pointer first then<br /> return the tx_cb that it points to. That way the txcb can be correctly<br /> cleaned up.
