Vulnerability details
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The orinoco_ioctl_set_auth function in drivers/net/wireless/orinoco/wext.c in the Linux kernel before 2.6.37 does not properly implement a TKIP protection mechanism, which makes it easier for remote attackers to obtain access to a Wi-Fi network by reading Wi-Fi frames.
