CVE-2023-53034 is an incorrect bitwise-shift vulnerability in the Linux kernel Switchtec non-transparent bridge driver. The switchtec_ntb_mw_set_trans function can be reached through ntb_mw_clear_trans, which supplies zero values for both the address and size parameters. This input causes the calculated xlate_pos value to become negative before it is used as the shift count in a BIT operation, producing an invalid negative shift exponent. The fix validates that xlate_pos is non-negative before performing the bit operation.
