Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/mlx5e: SHAMPO, Fix incorrect page release<br /> <br /> Under the following conditions:<br /> 1) No skb created yet<br /> 2) header_size == 0 (no SHAMPO header)<br /> 3) header_index + 1 % MLX5E_SHAMPO_WQ_HEADER_PER_PAGE == 0 (this is the<br /> last page fragment of a SHAMPO header page)<br /> <br /> a new skb is formed with a page that is NOT a SHAMPO header page (it<br /> is a regular data page). Further down in the same function<br /> (mlx5e_handle_rx_cqe_mpwrq_shampo()), a SHAMPO header page from<br /> header_index is released. This is wrong and it leads to SHAMPO header<br /> pages being released more than once.
