Summary
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: CT: Fix null-ptr-deref in add rule err flow In error flow of mlx5_tc_ct_entry_add_rule(), in case ct_rule_add() callback returns error, zone_rule->attr is used uninitiated. Fix it to use attr which has the needed pointer value.
