Details

In the Linux kernel, the following vulnerability has been resolved: tls: fix missing memory barrier in tlsinit In tlsinit(), a write memory barrier is missing, and store-store reordering may cause NULL dereference in tls{setsockopt,getsockopt}. CPU0 CPU1 ----- ----- // In tlsinit() // In tlsctxcreate() ctx = kzalloc() ctx->skproto = READONCE(sk->skprot) -(1) // In updateskprot() WRITEONCE(sk->skprot, tlsprots) -(2) // In sockcommonsetsockopt() READONCE(sk->skprot)->setsockopt() // In tls{setsockopt,getsockopt}() ctx->skproto->setsockopt() -(3) In the above scenario, when (1) and (2) are reordered, (3) can observe the NULL value of ctx->skproto, causing NULL dereference. To fix it, we rely on rcuassignpointer() which implies the release barrier semantic. By moving rcuassignpointer() after ctx->skproto is initialized, we can ensure that ctx->skproto are visible when changing sk->skprot.
