    I found possible memory leak in Windows kernel. How can I report it?


    Hello everyone,


    I gave up in about 5 minutes after trying to figure out where to actually report such bugs. I found a memory leak in Windows kernel ntoskrnl.exe that can be invoked from user-mode.


    Here is a proof-of-concept program. It is slow since it only allocates 2 bytes per call, but still it's something and it would be nice if it was fixed.

    Possible Memory Leaks in Windows 10

    A memory leak occurs when an application closes and fails to release all its RAM back to the operating system.

    The first step in dealing with a memory leak is to determine which application is leaking memory.

    The next step is to contact that application's technical support with complete details of the memory leak, since the developers will want to fix the problem ASAP.

    Memory leak issue

    The term "memory leak" means that an application fails to return all its RAM to the operating system when it exits. The leftover RAM is unusable to the operating system.

    Step one is to identify the application that is leaking memory. Step two is to contact the application's developers and provide as much detailed data on the memory leak as you can. For example: which processes are still in RAM after the application exits
    and how much RAM they occupy. Application developers never want their applications to leak memory and they will be grateful for the details you provide, particularly if they can replicate the leak on their own computers.

    I found possible memory leak in Windows kernel. How can I report it?

    is this memory leak?

    Hello RASHMIRANJAN1,

    I'm an independent advisor and hope this would address your questions.

    This is not a memory leak. A memory leak happens when a process or program failed to discard utilized memory when it is no longer in use. In that case, you would see a process or program consuming more and more memory over time.

    I wouldn't be worried about the paged and non-paged pools as they aren't excessively large in size. The paged pool is used to store handles of kernel objects, so it is normal to have some usage there. And non-paged pool is used by kernel and drivers of the
    operating system, so it is also normal for some usage there.
