      "title": "libceph: Fix potential out-of-bounds access in osdmap_decode()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nlibceph: Fix potential out-of-bounds access in osdmap_decode()\n\nWhen decoding osd_state and osd_weight from an incoming osdmap in\nosdmap_decode(), both are decoded for each osd, i.e., map->max_osd\ntimes. The ceph_decode_need() check only accounts for\nsizeof(*map->osd_weight) once. This can potentially result in an\nout-of-bounds memory access if the incoming message is corrupted such\nthat the max_osd value exceeds the actual content of the osdmap message.\n\nThis patch fixes the issue by changing the corresponding part in the\nceph_decode_need() check to account for\nmap->max_osd*sizeof(*map->osd_weight).",
