Why These Changes Fix the OOB Issue Without Changing Functionality: Preventing OOB Writes: By limiting write_size, we ensure that each call to kernel_write does not exceed the maximum allowed size, preventing potential OOB writes in lower-level functions. Handling Large len Values: The loop now correctly handles large len values by writing in chunks of at most MAX_RW_COUNT bytes, avoiding integer overflows. Safe Pointer Arithmetic: The calculation buf + pos remains within the bounds of the buffer because pos is carefully managed and checked for overflows. Consistent Behavior: The core logic and behavior of the function are preserved. It writes data from buf to filp until all len bytes are written, handling partial writes and errors appropriately. |

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 reStructuredText 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.
