🛡Fix memory leak in set_mempolicy_home_node system call

When encountering any vma in the range with policy other than MPOL_BIND or
MPOL_PREFERRED_MANY, an error is returned without issuing a mpol_put on
the policy just allocated with mpol_dup().

⚠️This allows arbitrary users to leak kernel memory(Dos).

🔥🔥🔥PoC of wfshbr64.sys LPE(Windows Kernel Mode Anti-Cheat Driver, CVE-2022-42046)

wfshbr64.sys and wfshbr32.sys specially crafted payload allows arbitrary user to perform bitwise operation with arbitrary EPROCESS offset and flags value to purposely elevate the game process to CodeGen Full protection by manipulating EPROCESS.Protection and EPROCESS.SignatureLevel flags (security hole as a feature).

⚠️The driver is signed by Microsoft hardware compatibility publisher that is submitted via Microsoft Hardware Program.
