Title
drm/imagination: Propagate map failures correctly from pvr_mmu_map_sgl()
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/imagination: Propagate map failures correctly from pvr_mmu_map_sgl() Map failure from pvr_mmu_map_sgl() interface was not returned correctly to pvr_mmu_map() interface. This resulted in pvr_mmu_map() interface to continue instead of returning an error to caller. Fix it by returning a proper error code from pvr_mmu_map_sgl() interface.

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.
