CVE-2022-49399

CVE-2022-49399 affects the Linux kernel tty driver for the goldfish port. In goldfish_tty_probe(), the port created by tty_port_init() can leak resources if error paths don’t destroy it; in goldfish_tty_remove(), the port must also be destroyed. The fix is to call tty_port_destroy() to release th...
