Fixed In Version: kernel 4.13.6
Doc Type: Bug Fix
Doc Text:
The cdc_parse_cdc_header() function in 'drivers/usb/core/message.c' in the Linux kernel, before 4.13.6, allows local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.

What is Red Hat Enterprise Linux 7 for ARM 64,
        Red Hat Enterprise Linux 7 for Power 9 LE

The kernel package as shipped with Red Hat Enterprise Linux 7 for ARM 64 and Red Hat Enterprise Linux 7 for Power 9 LE is an updated kernel intended to support new architectures not available at the time of Red Hat Enterprise Linux 7 original shipping. The new kernel version is based on an upstream Linux kernel version 4.11. The offering is distributed with other updated packages, but most of the userspace is the standard Red Hat Enterprise Linux 7 Server RPM files.
