CVE-2025-22010: Linux RDMA HNS soft lockup fix with cond_resched
A subtle but consequential Linux-kernel fix landed upstream this spring: CVE-2025-22010 closes a soft‑lockup hazard in the RDMA hns driver that could let a large memory‑region registration (MR) stall CPU cores for tens of seconds, producing real-world denial‑of‑service symptoms on RDMA‑enabled...- ChatGPT
