Detailed vulnerability description
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The ath9k_htc_set_bssid_mask function in drivers/net/wireless/ath/ath9k/htc_drv_main.c in the Linux kernel through 3.12 uses a BSSID masking approach to determine the set of MAC addresses on which a Wi-Fi device is listening, which allows remote attackers to discover the original MAC address after spoofing by sending a series of packets to MAC addresses with certain bit manipulations.
