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.

A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes possibly making the system inoperable.
