  "details": "In the Linux kernel, the following vulnerability has been resolved:  nfc: llcp: read llcp_sock-\u003elocal under the socket lock in getsockopt  nfc_llcp_getsockopt() read llcp_sock-\u003elocal before lock_sock(sk) and then dereferenced the cached pointer inside the locked region. llcp_sock_bind() assigns and clears llcp_sock-\u003elocal 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-\u003elocal 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.",
