CVE-2026-74675

A race condition in the Linux kernel's virtual terminal (vt) subsystem affects the kbd_keycode() function, which reads vc->port.tty without acquiring a proper tty reference. This races against con_shutdown(), which clears port.tty under a different lock, potentially leading to a use-after-free...
