Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/mlx5e: SHAMPO, Fix invalid WQ linked list unlink<br /> <br /> When all the strides in a WQE have been consumed, the WQE is unlinked<br /> from the WQ linked list (mlx5_wq_ll_pop()). For SHAMPO, it is possible<br /> to receive CQEs with 0 consumed strides for the same WQE even after the<br /> WQE is fully consumed and unlinked. This triggers an additional unlink<br /> for the same wqe which corrupts the linked list.<br /> <br /> Fix this scenario by accepting 0 sized consumed strides without<br /> unlinking the WQE again.
