CVE-2021-28361

A flaw was found in the SPDK iSCSI target. A NULL pointer dereference resulted from a text PDU sent with a zero-length, resulting in a crash of the SPDK iCSCI target process. The highest threat from this vulnerability is to system availability...

An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks and can exceed the PAGE_SIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI and has a length up to the maximum length of a Netlink message.

...

An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is adversely affected by the ability of an unprivileged user to craft Netlink messages.

...

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.
