Tested with KASAN (inline) under QEMU (guests 6.6.144 and 6.1.177), using a virtio-net device that advertises rss_max_indirection_table_length=512, i.e. larger than the driver's 128-entry VIRTIO_NET_RSS_MAX_TABLE_LEN. Boot time testing: - unpatched: KASAN slab-out-of-bounds write in virtnet_probe (both trees) - patched: clean, no KASAN report. Runtime testing: - patched: rewriting the full 512-entry table via ETHTOOL_SRXFHINDIR (reset and explicit full table) reports no KASAN bug. Thanks, Annie Kim
