Exploit públicoNo conocidosin código público localizado
En el kernel de Linux se ha resuelto la siguiente vulnerabilidad:
nfc: llcp: corregir la usurpación de SAP de WKS mediante coincidencia por prefijo en nfc_llcp_wks_sap()
nfc_llcp_wks_sap() compara solo service_name_len bytes, por lo que un service_name corto como "u" coincide con cadenas WKS más largas como "urn:nfc:sn:snep". Se corrige exigiendo una coincidencia exacta de longitud antes de strncmp().
