Oracle Linux 7 : Unbreakable Enterprise kernel (ELSA-2021-9112)

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2021-9112 advisory. - scsi: iscsi: Verify lengths on passthrough PDUs Chris Leech Orabug: 32634994 CVE-2021-27363 CVE-2021-27364 CVE-2021-27365 - scsi: iscsi: Ensure sysfs...

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.
