CVE-2022-49613

CVE-2022-49613 affects the Linux kernel serial driver 8250 console handover. When a console is enabled, univ8250_console_setup() runs before .dev is bound to the uart_port, so pm_runtime_get_sync() is skipped. Later, during handover, serial8250_console_exit() may call pm_runtime_put_sync() with a...
