CVE-2021-47541

CVE-2021-47541 targets the Linux kernel mlx4_en driver. In mlx4_en_try_alloc_resources(), mlx4_en_copy_priv() may free tmp->tx_cq on the error path, and later mlx4_en_alloc_resources() dereferences &tmp->tx_cq[t][i], risking a use-after-free. The fix adds a guard/check around mlx4_en_copy_p...
