An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI subsystem the transport's handle is available to unprivileged users via the sysfs file system at /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read the show_transport_handle function (in drivers/scsi/scsi_transport_iscsi.c) is called which leaks the handle. This handle is actually the pointer to an iscsi_transport struct in the kernel module's global variables.
