| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntls: fix missing memory barrier in tls_init\n\nIn tls_init(), a write memory barrier is missing, and store-store\nreordering may cause NULL dereference in tls_{setsockopt,getsockopt}.\n\nCPU0 CPU1\n----- -----\n// In tls_init()\n// In tls_ctx_create()\nctx = kzalloc()\nctx->sk_proto = READ_ONCE(sk->sk_prot) -(1)\n\n// In update_sk_prot()\nWRITE_ONCE(sk->sk_prot, tls_prots) -(2)\n\n // In sock_common_setsockopt()\n READ_ONCE(sk->sk_prot)->setsockopt()\n\n // In tls_{setsockopt,getsockopt}()\n ctx->sk_proto->setsockopt() -(3)\n\nIn the above scenario, when (1) and (2) are reordered, (3) can observe\nthe NULL value of ctx->sk_proto, causing NULL dereference.\n\nTo fix it, we rely on rcu_assign_pointer() which implies the release\nbarrier semantic. By moving rcu_assign_pointer() after ctx->sk_proto is\ninitialized, we can ensure that ctx->sk_proto are visible when\nchanging sk->sk_prot." |
