An issue was discovered in the Linux kernel before 4.20.15. The nfcllcpbuildtlv function in net/nfc/llcpcommands.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 nfcllcpbuildgb in net/nfc/llcpcore.c.
