Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: serial: core: check uartclk for zero
 to avoid divide by zero Calling ioctl TIOCSSERIAL with an invalid baud_base can result in uartclk being
 zero, which will result in a divide by zero error in uart_get_divisor(). The check for uartclk being zero
 in uart_set_info() needs to be done before other settings are made as subsequent calls to ioctl
 TIOCSSERIAL for the same port would be impacted if the uartclk check was done where uartclk gets set.
