      "title": "rbd: Reset positive result codes to zero in object map update path",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nrbd: Reset positive result codes to zero in object map update path\n\nIn a reply message to an RBD request, a positive result code indicates\na data payload, which is not allowed for writes. While\nrbd_osd_req_callback() already resets a positive result code for writes\nto zero, rbd_object_map_callback() does not. This allows a corrupted\nreply to an object map update to trigger the rbd_assert(*result < 0) in\n__rbd_obj_handle_request(). This happens, because\nrbd_object_map_callback() calls rbd_obj_handle_request() ->\n__rbd_obj_handle_request() and passes this positive result code. From\n__rbd_obj_handle_request(), rbd_obj_advance_write() is called, which\nleaves the positive result code unchanged and returns true. Therefore,\nthe if(done && *result) branch is executed in __rbd_obj_handle_request()\nand the assertion triggers.\n\nThis patch fixes the issue by adjusting the logic in the\nrbd_object_map_callback() path. A positive result code for an object map\nupdate is now reset to zero (similar to rbd_osd_req_callback()), and the\nmessage is subsequently handled the same way as if the result code was\nzero from the beginning. Additionally, a WARN_ON_ONCE() is added for\nthis case.",
