Description The Linux kernel contains a flaw within the libceph component. Specifically, the code previously used BUG ON which has been replaced with bounds checking for map->max osd. OSD indexes originate from network packets that are considered untrusted. The addition of boundary checks validates these indexes against map->max osd. This change addresses a potential issue where out-of-bounds access could occur due to improperly validated OSD indexes received from the network. The vulnerable code is related to the ceph get primary affinity() function.
