[Aircraft X] checked on and I advised him to expect vectors around an active Fire Fighting TFR for a Visual Approach. After a couple vectors and descents; he was crossing the 6700 ft. and 6000 ft. MVA (Minimum Vectoring Altitude) line. I realized he was already level at 6000 ft. I called the airport and cleared him for Visual Approach once he called the field in sight. I called the supervisor over and told him that I may have issued 6000 ft. to the pilot. When the supervisor listened to the tapes and I did clear him to 6000 ft. and he read back 6000 ft.
A TRACON Controller reported vectoring an aircraft below the Minimum Vectoring Altitude.
