    CVE-2025-21981: Linux Kernel ICE Driver aRFS Memory Leak DoS Risk

    The Linux kernel’s ICE driver contains a subtle but consequential memory-management bug that can quietly erode system availability: during certain reset-driven reconfiguration paths the driver double‑allocates accelerated Receive Flow Steering (aRFS) data structures without freeing previously...
