The iscsi_if_rx() function in 'drivers/scsi/scsi_transport_iscsi.c' in the Linux kernel from v2.6.24-rc1 through 4.13.2 allows local users to cause a denial of service (a system panic) by making a number of certain syscalls by leveraging incorrect length validation in the kernel code.

Statement:

This issue does not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 5 as the code with the flaw is not present in this product.

This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux  6, 7 and MRG-2. Future updates for the respective releases may address this issue.

This was fixed for Fedora with the 4.13.5 stable updates
