Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/mlx5: Clear port select structure when fail to create<br /> <br /> Clear the port select structure on error so no stale values left after<br /> definers are destroyed. That&amp;#39;s because the mlx5_lag_destroy_definers()<br /> always try to destroy all lag definers in the tt_map, so in the flow<br /> below lag definers get double-destroyed and cause kernel crash:<br /> <br /> mlx5_lag_port_sel_create()<br /> mlx5_lag_create_definers()<br /> mlx5_lag_create_definer()
