CVE-2026-92513Hinoki check available

Invalid memory access via queue-pair rollback race

Published Sep 17, 2026 · Updated Sep 17, 2026

Use-after-free in Linux 6.15 MANA RDMA queue-pair setup allows local users to trigger invalid memory access via failed table insertion. The mana_table_store_ud_qp() rollback removes the send-queue entry without draining references before RDMA core frees the queue pair. Reachability requires the MANA RDMA driver, a failed receive-queue insertion, and a concurrent completion lookup; a specific crash or code-execution outcome is not documented.
