+wpa_supplicant-2.6: Fix CVE-2018-14526
+
+[No upstream tracking] -- https://w1.fi/security/2018-1/unauthenticated-eapol-key-decryption.txt
+
+wpa: Ignore unauthenticated encrypted EAPOL-Key data
+
+Ignore unauthenticated encrypted EAPOL-Key data in supplicant
+processing. When using WPA2, these are frames that have the Encrypted
+flag set, but not the MIC flag.
+
+When using WPA2, EAPOL-Key frames that had the Encrypted flag set but
+not the MIC flag, had their data field decrypted without first verifying
+the MIC. In case the data field was encrypted using RC4 (i.e., when
+negotiating TKIP as the pairwise cipher), this meant that
+unauthenticated but decrypted data would then be processed. An adversary
+could abuse this as a decryption oracle to recover sensitive information
+in the data field of EAPOL-Key messages (e.g., the group key).
+
+Upstream-Status: Backport [https://w1.fi/cgit/hostap/commit/src/rsn_supp/wpa.c?id=3e34cfdff6b192fe337c6fb3f487f73e96582961]
