Last modified
CVE-2023-53034 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: ntb_hw_switchtec: Fix shift-out-of-bounds in switchtec_ntb_mw_set_trans There is a kernel API ntb_mw_clear_trans() would pass 0 to both addr and size. This would make xlate_pos negative.
