Описание
In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: fix WKS SAP hijacking via prefix match in nfc_llcp_wks_sap()
nfc_llcp_wks_sap() compares only service_name_len bytes, so a short service_name like "u" matches longer WKS strings like "urn:nfc:sn:snep". Fix by requiring exact length match before strncmp().
