The vulnerability of the `serial8250_tx_dmaFlush()` function in the `drivers/tty/serial/8250/8250_dma.c` file of the console TTY driver in the Linux kernel’s parallel port allows a attacker to cause a service failure.

The vulnerability of the serial8250txdmaFlush function in the drivers/tty/serial/8250/8250dma.c file of the console TTY driver in the Linux kernel’s serial port module is related to deficiencies in the system’s segmentation control. Exploiting this vulnerability could allow an attacker to cause a...

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...
