What to do
AI-suggested
A fix has been implemented in the Linux kernel to address this issue by introducing a new helper function that prevents allocation failures during queue page moves. Users should apply the official Linux kernel updates that include this fix. Patch status is not explicitly confirmed here; check the vendor advisory or Linux kernel release notes for the specific fixed versions and update accordingly.
Description
A vulnerability in the Linux kernel's RDMA core related to the handling of FRMR aging push to queue error flow has been resolved. The issue involved improper handling of failures when moving handles from an active queue to an inactive queue, potentially causing memory key leaks. The fix introduces a new helper function to safely move queue pages without allocation failures, simplifying error handling and preventing leaks.
