In routine c2h_wk_callback(() following a kmalloc() call, the error recovery is flawed. If the kmalloc() returns a pointer that is not NULL, and the following c2h_evt_read() fails, the code will leak that buffer. If the kmalloc() fails, a NULL dereference will occur in the following code.

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.
