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.
