Currently there are only 10 bytes to store the cpu-topology 'name' information. Only 10 bytes copied into cluster/thread/core names. If the cluster ID exceeds 2-digit number, it will result in the data corruption, and ending up in a dead loop in the parsing routines. The same applies to the thread names with more that 3-digit number. This issue was found using the boundary tests under virtualised environment like QEMU. Let us increase the buffer to fix such potential issues.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
