An issue was discovered in the Linux kernel before 4.20.15. The
nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If
the caller does not check for this, it will trigger a NULL pointer
dereference. This will cause denial of service. This affects
nfc_llcp_build_gb in net/nfc/llcp_core.c.
