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().
