      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Use RCU-safe iteration in dev_map_redirect_multi() SKB path\n\nThe DEVMAP_HASH branch in dev_map_redirect_multi() uses\nhlist_for_each_entry_safe() to iterate hash buckets, but this function\nruns under RCU protection (called from xdp_do_generic_redirect_map()\nin softirq context). Concurrent writers (__dev_map_hash_update_elem,\ndev_map_hash_delete_elem) modify the list using RCU primitives\n(hlist_add_head_rcu, hlist_del_rcu).\n\nhlist_for_each_entry_safe() performs plain pointer dereferences without\nrcu_dereference(), missing the acquire barrier needed to pair with\nwriters' rcu_assign_pointer(). On weakly-ordered architectures (ARM64,\nPOWER), a reader can observe a partially-constructed node. It also\ndefeats CONFIG_PROVE_RCU lockdep validation and KCSAN data-race\ndetection.\n\nReplace with hlist_for_each_entry_rcu() using rcu_read_lock_bh_held()\nas the lockdep condition, consistent with the rcu_dereference_check()\nused in the DEVMAP (non-hash) branch of the same functions. Also fix\nthe same incorrect lockdep_is_held(&dtab->index_lock) condition in\ndev_map_enqueue_multi(), where the lock is not held either.",
