kernel: serial: protect uart_port_dtr_rts() in uart_shutdown() too

A flaw was found in the Linux kernel's serial subsystem. This vulnerability occurs in the uartshutdown function, where a null pointer dereference can happen if the HUPCL flag is set. A local attacker could potentially exploit this flaw to cause a system crash, leading to a Denial of Service DoS...

CVE-2022-49613

In the Linux kernel, the following vulnerability has been resolved: serial: 8250: Fix PM usagecount for console handover When console is enabled, univ8250consolesetup calls serial8250consolesetup before .dev is set to uartport. Therefore, it will not call pmruntimegetsync. Later, when the actual...
