WebJun 16, 2024 · The best way to avoid memory leaks in C++ is to have as few new/delete calls at the program level as possible – ideally NONE. Anything that requires dynamic memory should be buried inside an RAII object that releases the memory when it goes out of scope. RAII allocate memory in constructor and release it in destructor, so that memory is ... Are you quite sure that cppcheck is not already able to check for kernel allocation leaks? The source code looks strongly like it treats kmalloc and so on just like malloc. Look at the testmemleak.cpp file in the cppcheck repository for example and you see test cases that exercise a bad kmalloc.
