Title
libceph: replace BUG_ON with bounds check for map->max_osd
Summary
In the Linux kernel, the following vulnerability has been resolved: libceph: replace BUG_ON with bounds check for map->max_osd OSD indexes come from untrusted network packets. Boundary checks are added to validate these against map->max_osd. [ idryomov: drop BUG_ON in ceph_get_primary_affinity(), minor cosmetic edits ]

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.
