      "title": "scsi: target: core: Fix iSCSI ISID use-after-free in REGISTER AND MOVE",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: target: core: Fix iSCSI ISID use-after-free in REGISTER AND MOVE\n\ncore_scsi3_emulate_pro_register_and_move() maps the PERSISTENT RESERVE OUT\nparameter list with transport_kmap_data_sg() and parses the destination\nTransportID with target_parse_pr_out_transport_id(). For an iSCSI\nTransportID (FORMAT CODE 01b), iscsi_parse_pr_out_transport_id() returns\nthe ISID in iport_ptr as a raw pointer into that mapped buffer.\n\nThe function then unmaps the buffer with transport_kunmap_data_sg() before\ndereferencing iport_ptr in strcmp(), __core_scsi3_locate_pr_reg() and\ncore_scsi3_alloc_registration(). When the parameter list spans more than\none page (PARAMETER LIST LENGTH > 4096), transport_kmap_data_sg() uses\nvmap() and transport_kunmap_data_sg() does vunmap(), so the kernel virtual\naddress backing iport_ptr is torn down and every subsequent dereference is\na use-after-free read of the unmapped region.\n\nKeep the parameter list mapped until iport_ptr is no longer needed: drop\nthe early transport_kunmap_data_sg() and unmap once on the success path,\nright before returning. The error paths already unmap through the existing\n\"if (buf) transport_kunmap_data_sg(cmd)\" at the out: label, which now runs\non every post-map error exit because buf is no longer cleared early. Only\nreads of the mapping happen while spinlocks are held; the map and unmap\ncalls remain outside any lock. The sibling caller\ncore_scsi3_decode_spec_i_port() already uses the buffer before unmapping it\nand is left unchanged.",
