In the Linux kernel, the following vulnerability has been resolved:

nfc: llcp: read llcp_sock->local under the socket lock in getsockopt

nfc_llcp_getsockopt() read llcp_sock->local before lock_sock(sk) and

then dereferenced the cached pointer inside the locked region.

llcp_sock_bind() assigns and clears llcp_sock->local under the same

socket lock, dropping the last reference on its error path. A

getsockopt() racing an in-flight bind() can observe the pointer, block

on lock_sock(), and then dereference a freed nfc_llcp_local once bind()

has unwound.

Move the llcp_sock->local read and the NULL check inside the

lock_sock(sk) region so bind() cannot mutate or free the pointer between

the load and the use. (NVD)
