Title
comedi: ni_atmio16d: Fix invalid clean-up after failed attach
Summary
In the Linux kernel, the following vulnerability has been resolved: comedi: ni_atmio16d: Fix invalid clean-up after failed attach If the driver's COMEDI "attach" handler function (`atmio16d_attach()`) returns an error, the COMEDI core will call the driver's "detach" handler function (`atmio16d_detach()`) to clean up. This calls `reset_atmio16d()` unconditionally, but depending on where the error occurred in the attach handler, the device may not have been sufficiently initialized to call `reset_atmio16d()`. It uses `dev->iobase` as the I/O port base address and `dev->private` as the pointer to the COMEDI device's private data structure. `dev->iobase` may still be set to its initial value of 0, which would result in undesired writes to low I/O port addresses. `dev->private` may still be `NULL`, which would result in null pointer dereferences. Fix `atmio16d_detach()` by checking that `dev->private` is valid (non-null) before calling `reset_atmio16d()`. This implies that `dev->iobase` was set correctly since that is set up before `dev->private`.

This calls\n`reset_atmio16d()` unconditionally, but depending on where the error\noccurred in the attach handler, the device may not have been\nsufficiently initialized to call `reset_atmio16d()`.  It uses\n`dev-\u003eiobase` as the I/O port base address and `dev-\u003eprivate` as the\npointer to the COMEDI device\u0027s private data structure.  `dev-\u003eiobase`\nmay still be set to its initial value of 0, which would result in\nundesired writes to low I/O port addresses.  `dev-\u003eprivate` may still be\n`NULL`, which would result in null pointer dereferences.\n\nFix `atmio16d_detach()` by checking that `dev-\u003eprivate` is valid\n(non-null) before calling `reset_atmio16d()`.

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.
