Summary
In the Linux kernel, the following vulnerability has been resolved: tty: serial: ip22zilog: Use platform device for probing After commit 84a9582fd203 ("serial: core: Start managing serial controllers to enable runtime PM") serial drivers need to provide a device in struct uart_port.dev otherwise an oops happens. To fix this issue for ip22zilog driver switch driver to a platform driver and setup the serial device in sgi-ip22 code.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
