The vulnerability in the function `serial8250_unregister_port()` of the `drivers/tty/serial/8250/8250_core.c` file, a driver for console TTY support on the serial port of the Linux kernel, allows a attacker to cause a service failure.

The vulnerability of the serial8250unregisterport function in the driver/tty/serial/8250/8250core.c file of the console support driver for the serial port in the Linux kernel is related to the failure to release resources after their useful period has ended. Exploiting this vulnerability could...

kernel: NULL pointer dereference in serial8250_isa_init_ports function in drivers/tty/serial/8250/8250_core.c

A NULL pointer dereference flaw was found in the Linux kernel’s UART 8250 functionality, in the way certain hardware architectures handled situations where default ports 0x2E8, 0x2F8, 0x3E8, 0x3F8 are not available. This flaw allows a local user to crash the system. The highest threat from this...
