CVE-2022-50557

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> pinctrl: thunderbay: fix possible memory leak in thunderbay_build_functions()<br /> <br /> The thunderbay_add_functions() will free memory of thunderbay_funcs<br /> when everything is ok, but thunderbay_funcs will not be freed when<br /> thunderbay_add_functions() fails, then there will be a memory leak,<br /> so we need to add kfree() when thunderbay_add_functions() fails to<br /> fix it.<br /> <br /> In addition, doing some cleaner works, moving kfree(funcs) from<br /> thunderbay_add_functions() to thunderbay_build_functions().
