      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nlibceph: Fix multiplication overflow in decode_new_up_state_weight()\n\nIf a message of type CEPH_MSG_OSD_MAP contains a (maliciously) corrupted\nosdmap, out-of-bounds memory accesses may occur in\ndecode_new_up_state_weight(). This happens because the bounds check for\nthe new_state part is based on calculating its length depending on a len\nvalue read from the incoming message. This calculation may overflow\nleading to an incorrect bounds check. Subsequently, out-of-bounds reads\nmay occur when decoding this part.\n\nThis patch switches the multiplication to use check_mul_overflow() to\nabort processing the osdmap if an overflow occurred. Therefore,\nosdmaps/messages containing large values for len that result in a\nmultiplication overflow are treated as invalid.\n\n[ idryomov: rename new_state_len -> new_state_item_size, formatting ]",
