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 ]
