**Name of the Vulnerable Software and Affected Versions** OpenBSD versions 6.2 through 6.3 **Description** The issue is related to incorrect I/O port access control on the i386 architecture, which can cause a Local Denial of Service (system crash) due to the `tss alloc` function in `sys/arch/i386/i386/gdt.c`. **Recommendations** For OpenBSD versions 6.2 and 6.3, consider applying a patch or fix that corrects the I/O port access control issue in the `tss alloc` function to prevent system crashes.
