AI-suggested
A fix is available that properly destroys FRMR handles on error paths to prevent resource leaks. Users should apply the updated Linux kernel versions that include this fix.
Description
A resource leak vulnerability in the Linux kernel's RDMA core was fixed by ensuring destruction of FRMR handles when the push to the pool fails. This prevents resource leaks caused by failed pool page allocations.
