CVE-2026-74299
In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix FRMR aging push to queue error flow Aging pools with pinned handles requires moving handles from the active queue to a non-empty inactive queue that might fail on new page allocation, we are currently not handling the fault and leaking any mkey that fails the push. Fix by Introducing push_queue_to_queue_locked() that fills the destination's partial tail page from the source and then splices the remaining source pages onto the destination, performing no allocation. Replace the per-handle move loop in age_pinned_pool() and the open-coded splice in pool_aging_work() with calls to the helper. As the helper cannot fail under memory pressure, removing a class of GFP_ATOMIC allocations under the pool lock and simplifying the error flow.
