Description
A flaw was found in the Linux kernel's RDMA/core component. When aging pools with pinned handles, a failure to move handles from the active queue to an inactive queue during new page allocation can lead to a memory leak. This occurs because the system does not properly handle the fault, resulting in the leakage of memory keys (mkeys).
